摘要:
地铁项目具有施工技术复杂、周边环境复杂、不可预见因素多等特点，导致安全事故多发。本文收集2001年~2019年地铁安全事故案例进行原因分析，并对危险源造成的损失成果程度进行问卷调查，借助主成分分析法研究危险源发生的频率及规律特点，研究危险源的相关性。将相关度高的危险源进行合并，从而得出六项关键危险源，为有效控制危险源提供参考。
The subway project has the characteristics of complex construction technology, complex surrounding environment, and many unforeseen factors, which lead to frequent safety accidents. This paper collects a number of subway safety accident cases from 2001 to 2019, extracts the causes, conducts a questionnaire survey on the degree of loss of hazards, and uses principal component analysis to study the frequency and regular characteristics of hazards, and to study the correlation of hazards. Combine the highly correlated hazards to obtain six key hazards, which can provide reference for effective control of hazards.
