基于模糊层次分析法的再生水厂基坑施工风险评价

Risk Assessment for Foundation Pit Construction in a Reclaimed Water Plant Using Fuzzy Analytic Hierarchy Process

为评价和解决基坑施工过程中的施工风险演化问题,基于模糊层次分析法(FAHP)构建了基坑施工风险评价体系,涵盖施工组织风险(人员)、工程环境风险(环境)、施工技术风险(技术)、施工作业风险(机械)、现场管理风险(管理)以及施工质量风险(材料)六个方面。结合某新建再生水厂基坑工程实例,评价再生水厂基坑工程风险等级,分析基坑工程施工重点风险因素,从而为基坑工程设计与施工提供基础参考。

Foundation pit construction faces complex site conditions and difficult construction techniques.In this paper,a foundation pit construction risk assessment system is constructed to evaluate and solve the risk evo-lution based on the fuzzy analytic hierarchy process(FAHP).This risk assessment system covers six risks inclu-ding construction organizational risk(personnel),engineering environmental risk(environment),construction technology risk(technical),construction operations risk(mechanical),site management risk(management)and construction quality risk(material).Taking a foundation pit construction of a newly built reclaimed water plant as an example,the risk level is assessed,and the key risk factors are analyzed.This study provides refer-ences for the design and construction of foundation pit.
