摘要
地下连续墙施工工序多且过程较为复杂,导致安全事故频发。文章对地下连续墙施工过程中的重要安全风险要素进行分析,首先通过访谈法、文献法及工程实践进行风险点收集;其次将风险点构成逻辑关联图;最后通过GeNIe软件形成贝叶斯网络图(BN),从诊断性分析、敏感性分析、关键致因链分析3个角度发现挖到地下危险管线、钢筋笼焊接不牢、钢筋笼起吊脱落吊钩为3个最重要的安全风险因素。相关研究可为业主方、总承包方、施工方、监理方分别采取针对性措施进行风险防控提供理论参考。
The construction of the underground diaphragm wall has various complicated processes,resulting in frequent safety accidents.The article analyzes the important safety risk elements in the underground diaphragm wall construction process.First,the risk points are collected through interview method,literature method,and engineering practices.Second,the risk points are constituted into a logical correlation diagram.Finally,a Bayesian network diagram(BN)was formed with the software GeNIe,where it was discovered that digging into underground hazardous pipelines,less durable welding on the reinforcement cage,and the hook of reinforcement cage falling off are the three most important safety risk factors from the perspectives of diagnostic analysis,sensitivity analysis,and key causation chain analysis.The relevant research can provide theoretical references for owners,general contractors,constructors,and supervisors to take targeted measures for risk prevention and control.
