    In order to promote the research on the correlation among safety humanology and safety behavior, the mode of action of safety humanity on safety behavior was explored. A assumption on safety humanity was made under the behavior mode of the individual, and factors influencing individual behavior were summarized from two aspects: safety physiology and safety psychology. According to the safety humanology and individual behavior characteristic, four individual behavioral elements were proposed, including safety motivation, safety skills, safety knowledge and safety values. On this basis, an individual safety behavior model based on safety humanology was built. Then, a process map of individual unsafe behavior was obtained from the model. The results indicate that safety humanity has an influence on safety behavior by influencing safety physiology and safety psychology. Besides, it provides important theoretical reference for accident analysis and prevention.

    In order to study the impacts of different factors on injury to the rider in a collision accident between automobile-motorcycle, based on a real case in the National Vehicle Accident Investigation System (NAIS), a model was built for collision between the front of the car and the right side of the motorcycle by using the PC-Crash software. Based on this basis, the influencing factors were identified and orthogonal experiments involving the car, the motorcycle, and the motorcycle rider were designed and carried out. The weights of them were analyzed. The influences of significant factors on the process were explored. Research shows that the car speed, rider's sitting high and hood front edge height from the ground are significant factors, that the smaller the rider's sitting high, the shorter the moment for the rider collision with the automobile, the injury to the rider, and that the greater hood front edge height from the ground, the smaller the injury to the rider.

    In order to deeply analyze the risk factors and their heterogenous impacts on severity of rollover accidents, a mixed logit model was developed based on 5 aspects of safety factors being human, vehicles, roads, environment and accidents. Model parameters were estimated by using the Monte Carlo method and elasticity values of the statistically significant variables were calculated. The model inputs were decided from 22 independent variables with statistical hypothesis testing of 5% significance level. The statistical results indicate that the severity is correlated with driver's gender, age, seatbelt usage, airbag deployment, ejection, alcohol use, drug use, risk driving behaviors, vehicle type, left-turning action, roadway section type, speed limit, accident location, accident date, adverse weather condition, light condition, and pavement condition, and that there is heterogeneity in the influencies of young and male drivers on the severity.

    Grinding, polishing, cutting and other machining processes generate high volumes of fine metallic dust. Due to different material and processing methods, the explosion risks of these kinds of industrial dust are uncertain. An improved dust explosion screening test method based on both Hartmann tube and 20 L siwek sphere was worked out and used to test 85 kinds of aluminum and its alloy dust generated in common machining process. XRF was performed to analyze the dust explosibility with different aluminum and iron content. The relationship between oxidation degree and dust explosibility was studied by using TG-DSC. The results show that the dust can be divided into three categories: certainly explosible, possibly explosible, and not explosible, that the explosion risk of dust is affected by particle size, composition, and oxidation among others, that most of the certainly explosible dust samples have more than 40% aluminum content or more than 70% iron content, and most of the possibly explosible dust have more than 40% iron content, and that the explosion risk of aluminum dust is inversely related to the degree of oxidation and dust samples are no longer explosible when the elemental content is less than 5.0%.

    The FEA method was used to build a full size model of large oil storage tank. Influences of foundation settlement on elephant foot buckling critical load of a large-scale, unanchored and external floating roof tank were analyzed in order to optimize the seismic design. Various items of tanks geometry including tank foundation, unanchored bottom with slope, tapered shell thickness, wind girders, stiffening rings, other attachments and appurtenances were taken into account thoroughly in the non-symmetrical full finite element model. On the basis of Fourier transform, foundation settlement was simulated by several combinations of harmonic waves. The radial deformation, buckling deformation mode and buckling strength were researched before and after foundation settlement. The influences of different orders of harmonic waves, harmonic wave amplitudes, trough and crest on elephant foot buckling critical load of tank were proved up while single harmonic settlement happened. The results show that foundation harmonic settlement has a negative influence on elephant foot buckling critical load, that the critical compressive stress of elephant foot buckling of tank shell decrease with the increasing harmonic amplitude of foundation settlement, and that the resistance capacity reduces as the harmonic order number rises under the same settlement.

Without considering the directionality of the pipeline network, the multi-attribute decision method Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) was used to analyze the nodes' importance. PageRank algorithm was used to analyze the importance ranking of nodes under the condition of considering the directionality of the pipeline network. The position and importance ranking were analyzed for the key nodes in the network comprehensively. The results show that the topology diagram based on the complex network theory can clearly show the position of the nodes in the pipeline network, that the node efficiency, the centrality of the nodes and the directionality of the network are all factors affecting the importance of the nodes in the network, and that the flow direction of the network has a greater impact on the important nodes.

    In order to build an effective finite element model for safety evaluation of bridge structure, a calibration method of mechanical parameters based on the diagnostic test data for bridge structure was worked out. Singularity of sensitivity matrix in sensitivity analysis was avoided by means of regularization of both the mechanical parameters and the load effect parameters. For improving converge efficiency and convergence of the optimization objective function, a penalty function was introduced into it. In addition, by calibrating the finite element model of an existing bridge structural mechanics parameters, the reason for the large deviation between the test data and the load effect value based on the structural design parameters was specified, and the effectiveness of the proposed method was verified. The results show that the mechanical parameter calibration of bridge structure based on diagnostic test can effectively solve the problem of large difference between analysis method and test result, and that it can provide a feasible method for evaluating objectively the safety of bridge structure.

    The spatial Markov chain method was adopted to explore the role of regional spatial relationships in the evolution of construction safety statues. Firstly, the construction safety statues of each province was classified into 5 different clusters by the accident rates in each province from 2012 to 2016. Then, traditional Markov chain method and spatial Markov chain method were used to construct a transfer matrix of construction safety statues respectively. Finally, the transferring probabilities of the construction safety statues in provinces of China from 2012 to 2016 were calculated under the condition of spatial lags, to analyze the influencing directions and extent of contractors from neighboring provinces on provinces with different construction safety statues. Results show that the spatial Markov chain method was more accurate in presenting the effect of regional spatial relationship on the evolution of construction safety statues, that trans-provincial contracting has a positive effect on the provinces with general and poor construction safety, but has a negative impact on the provinces with excellent and good construction safety,and that provinces with better construction safety are more resistible to negative impacts.

    In order to effectively and accurately predict the absolute gas emission of the mining face, a VMD-DE-RVM interval prediction method was worked out for absolute gas emission from a mining face based on VMD method, DE algorithm and RVM principle. For working out the method, the absolute gas emission was decomposed into several intrinsic mode components by VMD method and the local characteristics were analyzed. RVM prediction models were built for the intrinsic mode component, and the model parameters were optimized by DE algorithm to improve the prediction accuracy. Prediction results of the components were weighted and superimposed to obtain an absolute gas emission prediction result. A prediction result comparison was made between the three models. The results show that the method worked out by the authors can weaken the local characteristics of gas emission, and the prediction interval effectiveness is 100%, the average absolute error is 0.096 m3/min and the average relative error is 2.43% when the confidence is 95%, and the prediction accuracy is improved.

    For the sake of preventing thermal runaway, the Fluent software was applied to execute CFD simulation of an industrial scale reactor to explore the influences of hot spots on the thermal runaway process of TBPA. The divergence criterion was adopted as the critical criterion for thermal runaway. Physical parameters of TBPA thermal decomposition were set on the basis of analytical results of the thermal dynamics and the decomposition products. Multiple reference frame model was used to simulate the rotation of the agitator in the reactor. The effects of transient hot spots at the top, 1/4, 1/2 and 3/4 liquid height of the reactor and the bottom on the thermal runaway process were respectively investigated. It is found that thermal runaway of the system will advance greatly when there are hot spots, that hot spot at the bottom triggers off global thermal runaway fastest, the most dangerous situation, and that rapid detection of local thermal runaway caused by possibly-existed hot spots requires setting two temperature probes, one atthe top zone of the liquid having a distance (to the axis) being approximately 1/2 of the radius and the other one in the retention area below the agitator.

    In order to accurately estimate the radioactive source terms in the nuclear accident consequence assessment, the BPNN inversion model of nuclear accident source terms was optimized. A PCA-BPNN assessment model was built after reducing the number of factors influencing the terms from 10 to 6. The cumulative contribution rate of the 6 factors was greater than 85%. Random forest algorithm was used to calculate values of importance of the influence factors to remove the wind direction and the height of the mixed layer, and to build an RF-BPNN assessment model. The estimation results by the above three models were analyzed. The results show that compared with BPNN model, PCA-BPNN model and RF-BPNN model have shorter estimation time and smaller error, the two can reflect the source information of the accident truthfully, and that RF-BPNN model has better accuracy and stability than PCA-BPNN model.

    In order to prevent seepage failure of mountain riverbank and riverbank collapse, on the basis of Boussinesq unsteady seepage differential equation, an analytical solution was derived for the location of phreatic line in the mountain riverbank under the combined action of rainfall and water level fluctuations. The solution was verified to be correct by comparing the finite element simulation results. A practical mountain riverbank was taken as the research object, the evolution of the seepage characteristics of the riverbank at different stages during and after heavy rainfall were revealed quickly with analytical solution of phreatic line. The results show that at beginning of rainfall, the phreatic line is mainly uplifted by infiltration of rainwater, and direction of seepage is facing the riverside.During the continued rainfall, the phreatic line is lifted by the combined action of rainwater infiltration and the rising water level, and the seepage direction is still towards riverside.After the rainfall, the phreatic line near the river first gradually rises to the highest position because of continuous rises of the water level, and then gradually decreases as the water level decreases,the direction of seepage flow gradually shifts from towards riverside to towards landside, and then again towards riverside.The significant changing range of seepage direction and gradient is concentrated near the riverside.

    This paper takes a real block as the study area, simulating the radionuclides dispersion under adirty bomb attack in this block based on the Euler numerical model. Then features of the radionuclides dispersion with complex street geometry and different wind field conditions are examined and concluded. Results show that the radiological risk grows up with the increase of wind speed when it is under 20 m/s with the same wind direction, that when wind speed is 10 m/s, the sum of the radiological risk reaches the maximum value at the exits downwind while it is minimum if the wind speed is 6 m/s, that higher wind speed witnesses more significant influence of the street complexity on the radionuclides dispersion, that the radionuclides near the source is easy to form a large high-concentrated area and present a Gaussian distribution if the wind speed is slower than 2 m/s, that in circumstance of dirty bomb attacking, staying in the downwind area near the buildings, as well as the areas with densely or open circular buildings should be avoided, and evacuating from the adjacent exits should also be forbidden.

    GCM was applied to research the quality of the environment of a certain gold mine in Shandong as a function of the exploitation depth. Monitoring tests and investigations were carried out on environmental factors, such as O2, CO2, dust, toxic gases, micro-climate, noise and illumination for the mining faces being at exploitation depths of -30, -70, -110, -150, -190, -230 and -300 m respectively. Trends in changes of environmental factors in the underground mining faces were analyzed. An assessment of comprehensive environment quality was made for the mining faces via introducing GCM integrated with G1 method for determining the weight values of the environmental factors. A questionnaire survey on subjective satisfaction was carried out into a part of staff of the gold mine. The results show that there is a negative correlation between the environment quality grade(EQGs) of mining face and the exploitation depth of mining face, and obtained findings coincide with the assessment results via GCM.

    Based on the FTA model inference algorithm, the minimum cut set (path set) and structural importance of the root nodes were determined, and the occurrence and evasion scenario of runway conflict were analyzed accordingly. By the bidirectional reasoning technology of BN, the key risk influencing factors were analyzed, and by the risk factor polymorphism, risk assessment was conducted. Based on the risk analysis conclusion, risk control measures were proposed. The results of the study indicate that runway conflict risk at water aerodrome is most sensitive to the meteorological and hydrological factors, followed by the factors such as the frequency of passing vessels and the cleanliness of the sea runway, therefore, release control should be enforced strictly, and that safety management and personnel factors having a greater impact on runway conflict risk at water aerodrome should be the key point of risk management.

    In order to solve the problem of emergency logistics facility location under uncertain conditions, an IIF-ER based model combining was built. For building the model, the interval intuitionistic fuzzy value (IIFV) was used to express the expert evaluation information in view of the uncertainty of index evaluation. Considering that the traditional IIF has the problem of information loss in information integration, the method of ER integration was used to integrate the evaluation information. The method of TOPSIS was used to sort the location of emergency logistics facilities. Finally, an example of establishing emergency logistics facilities in a certain city was given to verify the effectiveness of the model. The results show that the model can be used to solve the problem of emergency logistics facility location decision under uncertain conditions, at the same time, it can ensure the quality of decision-making and shorten the decision time.
