基于层次分析法的立交桥满堂支架施工风险评估

Construction Risk Assessment of Overpass All-around Support Based on Analytic Hierarchy Process

文章以凤凰岭高速-环路立交桥为工程背景,基于定性与定量相结合的层次分析法对立交桥满堂支架施工中的风险源进行分析,建立了立交桥满堂支架施工危险性分析的递阶层次结构模型,根据专家调查法建立各层次的风险判断矩阵,并根据各分区的权重值进行排序,从而实现对立交桥满堂支架施工事故的有效预防和管理。

With Fenghuangling Expressway-loop overpass as engineering background, and based on the combined qualitative and quantitative analytic hierarchy process, this article analyzed the risk source of overpass all-around support construction,established the hierarchical-level structure model for the risk analysis of overpass all-around support construction, and established the risk judgment matrix of each level according to expert investigation method,with the sorting according to the weight of each district, so as to achieve the effective prevention and management of overpass all-around support construction accident.
