摘要
提出了影响盾构法地铁施工安全的影响因素集合,并对集合中24个影响因素进行PCA降维处理,对得到的9个主成分进行整合重组,形成计划、技术、环境、组织监控4类安全管理评价指标,建立基于主成分分析的地铁施工安全管理评价指标体系,利用Shapley值基本原理计算基于非可加测度的各指标权重,并结合Fuzzy理论构建地铁施工安全管理评估模型,对某实际工程分析盾构法地铁施工安全管理效果,确定了影响盾构地铁施工安全的关键因素,并给出了针对盾构法地铁施工的安全管理改进意见,通过模型信息反馈指导现场施工,验证了该模型的可行性。
This paper proposes an index set of safety management of shield metro construction,then realizes the PCA dimension of the 24 indexes in the set. By integrating and restructuring the 9 principal components,this paper gets four main index such as plan management index, technology management index,environment management index,and organization monitor management index. The Index System of safety management of shield metro construction based on PCA is built up. This paper use the Shapley value to calculate the weights of index and these weights are Non-additive measures. Combined with Fuzzy theory,the safety management model of shield metro construction is established. Finally,by the practical engineering in shanghai,this paper analyzes the result of safety management,and presents some suggestions for the shield metro construction. This model can guide the construction site through the information feedback which confirms the scientific of this math model.
