基于层次分析法的桥梁施工风险识别及评估分析

Risk Identification and Evaluation Analysis of Bridge Construction Based on Analytic Hierarchy Process

由于桥梁施工过程中存在大量影响施工安全的不确定性因素,为保障桥梁施工过程中企业和作业人员的生命财产安全,本文通过对桥梁施工过程的风险源进行分析辨别,运用层次分析法,将导致桥梁施工风险事故的原因进行分层,对可能导致桥梁施工安全事故的风险因素进行分析评价.分析结果表明:管理缺陷对桥梁施工风险事故影响最大,是导致事故的最主要因素.

There are many uncertain factors which affect the construction safety in the process of bridge construction.In order to ensure the safety of life and property of enterprises and workers during bridge construction,this paper analyzes and identifies the risk sources in bridge construction process,using the analytic hierarchy process to stratify the causes of bridge construction risk accidents,and analyzing and evaluating the risk factors which may result in bridge construction safety accidents.The analysis results show that the management defect has the greatest influence on the bridge construction risk accidents,and it is the most important factor that leads to the accidents.
