基于Shapley值和Fuzzy模型的地铁盾构施工安全管理研究

Study on Safety Management Model of Shield Subway Construction Based on Shapley Value and Fuzzy Model

根据地铁盾构施工的具体过程,对影响地铁盾构施工安全的因素进行收集并归类划分,建立地铁盾构施工安全管理评价指标体系。利用Shapley值来确定指标体系中存在关联性的各指标权重,采用模糊理论对各级指标进行模糊综合评价,构建了基于Shapley值和Fuzzy理论的地铁盾构施工安全管理评价模型,对地铁盾构施工的安全管理过程进行研究。最后以某地铁盾构施工项目为例,对其施工安全管理过程进行了研究,由案例评价结果可知,将Shapley值和Fuzzy模型应用在地铁盾构施工的安全管理上是可行的,能提高地铁盾构施工安全管理水平。

In this paper,according to the specific construction process of the shield subw ay,it collects and classifies influence factors affecting the safety of shield subw ay construction at first,and sets up evaluation index system of shield subw ay construction safety management. Then Shapley value is used to calculate the w eight of each index in the index system based on the additive measure,and combines w ith Fuzzy theory to proceed fuzzy comprehensive evaluation for all levels of indicators,building the appraisal model of shield subw ay construction safety management based on Shapley value and Fuzzy theory,and studying safety management of shield subw ay construction process. Finally,taking a shield subw ay construction project as an example,this paper studies its process of construction safety management,and puts forw ard improvement opinions to shield subw ay construction safety management according to the evaluation results; the feasibility of the model is verified by calculation on the shield subw ay construction safety management.
