摘要: 为减少旧工业建筑改造(ROIB)施工阶段安全事故,提高施工阶段的安全性,针对旧工业建筑特性研究施工安全影响机制。根据ROIB具体施工情况识别风险影响因素,采用主成分分析法(PCA)分析影响因素,并构建指标体系;基于指标体系建立结构方程模型(SEM),并对模型进行影响机制的验证分析;从影响强度和影响路径2方面机制解析SEM的分析结果。结果表明:各外源潜变量对施工安全绩效影响在0.05水平均具有显著性;影响因素的重要程度排序由大到小依次为人员因素、施工机械与材料、施工环境与管理、技术因素。

Abstract: In order to reduce the safety accidents in the construction stage of ROIB reconstruction and improve the safety of construction phase, the construction safety impact mechanism is studied according to the characteristics of old industrial buildings. According to the specific construction conditions of ROIB, the risk influencing factors are identified, and the influencing factors are analyzed by PCA and the index system is constructed,SEM is established based on the index system, and the influence mechanism is verified and analyzed, SEM analysis results are analyzed from the influence intensity and the influence path. The results show that the influence of external potential variables on construction safety performance is significant at 0.05 level, and the order of the importance of the factors is personnel factor, construction machinery and materials, construction environment and management and technical factors.

Key words: reconstruction of old industrial buildings(ROIB), construction safety, recycling, principal component analysis (PCA), structural equation modeling (SEM)
