Interval non-probabilistic reliability analysis of support structures for deep tunnel LI Xiang, WEI Heng, WANG Jingtong China Safety Science Journal    2023, 33 (12): 67-76.   DOI: 10.16265/j.cnki.issn1003-3033.2023.12.0546 Abstract （527）   HTML （2）    PDF（pc） （5248KB）（285）       Knowledge map    Save Aiming at the current situation of a lack of uncertain data, an interval non-probabilistic tool was introduced to perform a preliminary investigation in the domain of reliability analysis for the support structures of the deep tunnel. Firstly, the mechanism of the shearing slip displacement in the weak rock surrounding the deep tunnel was taken as an illustrative example, and a method was developed to calculate the total support resistance by using the combined support modes. Subsequently, based on the framework of the interval non-probabilistic theory, and meanwhile considering the influence caused by the interval extension problem, the applicability of the interval non-probabilistic tool was discussed for reliability study on the support structures of the deep tunnel. Eventually, a fluctuation range was defined to characterize the variations of the interval used for those uncertain parameters, and on this basis the difference for the level of those effects of fluctuations regarding a single-parameter and multiple-parameters coupling on the reliability of the support structures was revealed via the sensitivity analyses. The results manifest that the greater the fluctuation range of the interval for the uncertain parameters, the smaller the value of the non-probabilistic reliability index will be. Moreover, the larger the number of uncertain parameters involved in the fluctuation coupling, the higher the decrease in the value of the non-probabilistic reliability index will be. Hence, this situation makes the unfavorable effects on the reliability of the support structures more significant. Table and Figures | Reference | Related Articles | Metrics | Comments（0）

Overview of recognition methods of pedestrian abnormal behaviors in public places ZHAO Rongyong, WEI Bingyu, ZHU Wenjie, ZHENG Chengyuan, LI Haonan China Safety Science Journal    2024, 34 (2): 83-93.   DOI: 10.16265/j.cnki.issn1003-3033.2024.02.1125 Abstract （473）   HTML （15）    PDF（pc） （6468KB）（218）       Knowledge map    Save The purpose of this research is to clarify the research progress of the theory and technology of pedestrian abnormal behavior recognition in public places. Firstly, with the help of China National Knowledge Infrastructure (CNKI) and the Web of Science (WOS), a broad definition and universal characteristics of abnormal pedestrian behavior in public places were given. The existing research results related to abnormal behaviors were divided into three categories: harmful behaviors, dissociable behaviors and violations. Then, from the perspective of data and technological foundations, the existing abnormal behavior recognition methods were divided into four categories: artificial design, human skeleton, Red Geen Blue(RGB) images and wearable sensors. Secondly, this study sorted out the abnormal behavior datasets of mainstream populations both domestically and internationally, and analyzed the performance of relevant algorithms on the datasets. Finally, the limitations of existing research methods in available datasets and data fusion detection were summarized, and future research directions and optimization suggestions were provided. The results indicate that these four types of abnormal behavior recognition methods have their own advantages and disadvantages. It is necessary to construct a diversified, well-defined and high-quality international benchmark dataset of abnormal behaviors among the crowd. Future research should focus on robust and accurate methods, models, and algorithms for identifying abnormal behaviors, explore multi-dimensional data fusion complementary detection methods, improve the application scenario consistency and adaptability of the theoretical results of abnormal behavior recognition, and eventually enhance the level of public place crowd safety governance.

Experimental study on spalling failure of deep hard rock tunnels with different lithology and cross-section shapes LI Xiang, MIAO Sen, YANG Bo China Safety Science Journal    2024, 34 (8): 108-119.   DOI: 10.16265/j.cnki.issn1003-3033.2024.08.0597 Abstract （440）   HTML （0）    PDF（pc） （31847KB）（63）       Knowledge map    Save To explore the influence of the lithology and cross-section shape on spalling failure properties of deep hard rock tunnels, indoor true triaxial tests on spalling failure were performed. Firstly, two types of rock samples (marble and granite) and two typical cross-section shapes (high side wall gate arch shape and horseshoe shape) samples in practical applications were selected. Then, the failure characteristics under the influence of different lithology and cross-section shapes were analyzed from the three aspects including spalling failure mode, spalling rock plate characteristics, and the characteristic stress during spalling. Finally, numerical simulation was conducted to explore the corresponding displacement and stress distribution characteristics during the development and propagation of the cracks. Furthermore, the spalling failure characteristics of deep hard rock tunnels were investigated. The results indicated that the slab peeling and opening failure phenomenon for the marble sample was more significant than the granite one in terms of spalling failure mode during the test process. Moreover, the cross-sectional contour range involved in spalling failure for the horseshoe shape sample was smaller than the high-side wall gate arch shape. Different lithologies presented different flaked rock slab shapes for different flaked rock slab characteristics. Compared with the high-side wall gate shape, the flaked rock slabs near the outer layer relevant to the curved wall arch sample were more slender. For the characteristic stress during spalling, the granite sample had a larger threshold at the beginning of the spalling and a faster rate for the evolution process of the spalling failure compared with the marble one. Furthermore, compared with the horseshoe shape sample, the characteristic stresses of the high-side wall gate arch sample were higher from the beginning of plate cracking to the occurrence of obvious plate cracking failure. The area with large displacement in the numerical simulation was mainly observed on the side wall of the hole. The farther away from the side wall, the smaller the displacement. Moreover, the major reason the spalling occurs can be attributed to the tangential stress concentration. Table and Figures | Reference | Related Articles | Metrics | Comments（0）

Generation mechanism of weak prevention in process of accident risk governance ZHANG Jian, HU Chunyan China Safety Science Journal    2024, 34 (12): 24-33.   DOI: 10.16265/j.cnki.issn1003-3033.2024.12.0580 Abstract （436）   HTML （0）    PDF（pc） （2747KB）（0）       Knowledge map    Save In order to promote the precise governance goals of accident risks, a research method combining process-tracking based on actor network theory and case comparative analysis was adopted to study the weak prevention generation mechanism in the process of accident risk governance. Firstly, the technical environment for analyzing the evolution process of accident risk was clarified, including prepositive contexts, structural scenarios, and developmental circumstances, as well as the analysis logic based on Lens Model and dimensions of time, space, and structure, to provide a research foundation for the integrity analysis of accident risk production process. Secondly, based on the case comparative analysis of the tracking of the interaction process between different types of actors and risks, the role change picture of the core actors, homeowners and rainstorm, in the process of accident/disaster risk governance and accident/disaster generation was presented integrally. Finally, a comparative analysis and reflection of case studies based on tracking the interaction between different types of actors and risks were summarized, and the essence and generation mechanism of weak prevention in the process of accident risk governance were proposed. The results indicate that the mixed interaction between human and non-human actors can continuously activate the emergence and mutual construction process of new actors, new intersectionality, and new vulnerabilities in the system, subsequently resulting in the non-stationary evolution of accident risk production environment and risk structure, which leads to intervention failure and recurrence of weak prevention in the process of accident risk governance.

Investigation of safety & security attributes WU Chao China Safety Science Journal    2023, 33 (5): 1-8.   DOI: 10.16265/j.cnki.issn1003-3033.2023.05.0926 Abstract （411）   HTML （3）    PDF（pc） （1511KB）（217）       Knowledge map    Save The words safety & security (simplified as SS) are the most basic terms of SS discipline. Only by clarifying SS characteristics, connotation, extension and development timely can we better understand SS science and study its development law. Therefore, using the methods of historical analysis and logical thinking and reasoning, this paper expounded the dimension and complexity of SS, the specialty and popularity of SS, the ontology and epistemology of SS, the natural and social attributes of SS, and the classification method of SS definitions. Then the nature and characteristics of the discipline of SS science were inferred. The research conclusions are as follows: discussing SS issues requires a common language environment. The SS goes beyond the scope of technological terminology. Since SS is a reflection of human understanding, it is difficult for SS issues research to enter the ontological level. The natural and social characteristics of human beings determine that SS has dual attributes of nature and society, and the eternal nature of contradictions, which leads to the complexity of SS issues and the diversity of its definitions. The paradigm of giving SS definition through "preset + SS" can better express the scope and margin of SS. Reference | Related Articles | Metrics | Comments（0）

Secondly, taking "2·22" particularly serious collapse accident in Inner Mongolia Xinjing coal mine as an example, the accident was analyzed based on 24Model. Finally, combined with the above analysis and research results, the accident prevention countermeasures and suggestions in line with the current situation of coal mine safety production in China were put forward. The analysis and research results show that the number of major accidents and deaths in coal mines has shown an overall downward trend, and the level of coal mine safety production in China has significantly improved since the 12th Five Year Plan. Gas accidents are still the main accidents in coal mines in China, accounting for 51%. The fourth quarter of each year is a period of high incidence of coal mine accidents, accounting for 30.43% of the total number of accidents. Affected by geological conditions and occurrence, accidents often occur in the main coal producing areas. The proportion of accidents caused by unsafe human behavior is as high as 74%. When there are hidden dangers at both the individual and organizational levels and the dual prevention measures are not in place, accidents are likely to occur. Countermeasures and suggestions for reducing coal mine safety accidents are put forward from four dimensions, including safety supervision, strengthening safety through science and technology, team development and safety culture.

Comparative analysis study of STPA and 24Model SONG Wei, FU Gui China Safety Science Journal    2023, 33 (6): 1-10.   DOI: 10.16265/j.cnki.issn1003-3033.2023.06.1172 Abstract （387）   HTML （5）    PDF（pc） （2046KB）（213）       Knowledge map    Save In order to improve and develop the accident causation theory, the four aspects of STPA and 24Model, the underlying theory, relevant definitions, analysis process and analysis difficulty, were compared and analyzed, and applied to different cases respectively. The results of the study show that both models have a strong theoretical foundation. The research object of STPA is the loss of system. It performed better at system interaction study, but the complexity is high and the research error is large, so it is more suitable for single-accident analysis. In contrast, the research object of 24Model is event in the organization. The classification of accident causes is clearer and more universal. The model is simple, the research error is small, and it is commonly used for both single-accident and multi-accident analysis. Both methods are of good extensibility. In terms of application, STPA is clear on the connection between hazards and losses. However, this method is complex and subjective on accident causation, which also lacks research on inter-organizational interactions. In contrast, 24Model is more comprehensive and clearer, but it fails in the analysis of inter-organizational interaction and design defects.

Detection and resolution strategy of UAV low-altitude conflict based on geometric relations YUE Rentian, MA Zhaofei China Safety Science Journal    2023, 33 (5): 112-120.   DOI: 10.16265/j.cnki.issn1003-3033.2023.05.2049 Abstract （385）   HTML （2）    PDF（pc） （2192KB）（369）       Knowledge map    Save In order to ensure the flight safety of multi-rotor UAVs in low-altitude airspace, a conflict detection model and conflict resolution strategy for UAV low-altitude flights were proposed. According to the current Automatic Dependent Surveillance-Broadcast (ADS-B) data of the UAV, the interactive multi-model volumetric Kalman filtering algorithm (IMM-CKF) was used to predict the trajectory of the next stage, and the potential conflict objects were screened. According to the characteristics of the flight protection area, the AABB bounding boxes of the two aircrafts are constructed, and the three-dimensional collision detection algorithm was used to judge whether the two aircraft conflict, and SOSA flight conflict resolution strategy was proposed. Finally, four common conflict scenarios were constructed. The proposed algorithm was used to detect flight conflict. The SOSA combined resolution strategy and the traditional resolution strategy, such as the height adjustment method, the direction adjustment method and the speed adjustment method were used to resolve the flight conflict according to the situation. The results show that the flight conflict detection method based on the AABB bounding box can quickly detect conflicts within 0.02 s, and the use of SOSA combined resolution strategy can reduce the increase of the flying distance to less than 5% of the direct flight distance compared with the traditional resolution strategy. The conflict detection method is robust in real time, the complexity of the resolution strategy operation is low, and the payment distance is small during the conflict resolution process.

Based on 24Model, 87 typical mine accident investigation reports were analyzed, and a framework of mine accident cause classifications was obtained. A corpus was constructed for each type of accident cause constructed. The NLP was used for processing each type of cause text of the corpus and training the fastText model to realize the automatic recognition and classification of accident cause text. The method proposed was compared with TextCNN and the other two classical models. The results show that a total of 21 types of accident causes and 6 684 training corpus are obtained, the accuracy of fastText after training can reach 98.92%, and the comprehensive performance is better than the other three methods. The accident text mining system is developed based on 24Model and NLP, which can analyze and process the accident text information quickly and further detail the cause of the accident investigation report, which is convenient for the case study and statistical analysis.

A new concept model of safety culture and its evaluation application CHEN Weijiong, HAN Weijia, LI Xin, KANG Yutao, JIAO Yu, FENG Xiang China Safety Science Journal    2023, 33 (6): 11-19.   DOI: 10.16265/j.cnki.issn1003-3033.2023.06.1915 Abstract （363）   HTML （4）    PDF（pc） （1778KB）（178）       Knowledge map    Save In order to improve the level of safety culture construction in the shipbuilding industry, based on the definition of safety culture and objective reality, a new concept model of safety culture (SV-MMEMS) was proposed by integrating safety values (SV) and man-machine-environment-management system (MMEMS) model. Based on the five dimensions of safety values, man, machine, environment, and management of this model, a survey was conducted on the W shipbuilding enterprise. After data processing, such as project analysis, reliability analysis, validity testing, and factor analysis, a safety culture evaluation index system for the shipbuilding industry was constructed, consisting of five dimensions, 14 first-level indicators, and 33 second-level indicators. A second-order confirmation factor analysis model for safety culture, as well as a causal path analysis model among safety culture influencing factors, was constructed using AMOS. The findings demonstrated a favorable interaction relationship between the five elements, with "SV" acting as the nucleus and the path conefficients of each element in "MMEM", which were, respectively, 0.766, 0.553, 0.720, and 0.839. The ratio is 26.6%, 19.2%, 25.0%, and 29.2% after standardization, and organizational management elements were determined to have the biggest influence on the development of W shipping enterprise's safety culture. SV-MMEMS has considerable development and application prospects in the construction and evaluation of safety culture in enterprises and organizations.
