基于DEMATEL-ISM的地铁施工期风险因素分析

Analysis of risk factors during subway construction period based on DEMATEL-ISM

为了减少地铁施工期事故的发生,从事故调研、文献参考、现有施工规范3个方面识别11个地铁施工初始风险因素。利用决策实验室分析法(DEMATEL)计算11个影响因素的影响度、中心度以及原因度,排除风险因素作用较小的部分,结合解释结构模型(ISM)将10个风险因素划分为4个层级,确定各影响因素间的内在联系,为后续对地铁施工期风险管理工作提供参考。

In order to reduce the occurrence of accidents during subway construction,11 initial risk factors of subway construction were identified from three aspects:accident investigation,literature reference and existing construction specifications.The decision laboratory analysis method(DEMATEL)was used to calculate the influencing,centrality and causal degree of 11 influencing factors,and the parts with less role of risk factors were excluded.Combined with the explanatory structure model(ISM),the 10 risk factors were divided into four levels,and the intrinsic relationship between the influencing factors was determined.It provides a reference for the subsequent risk management work during the construction period of the subway.
