城市明挖隧道基坑施工危险源辨识及应对措施

Identification and Corresponding Measuresof Hazards for Construction of City Open-cut Tunnel Foundation Pit

基坑工程是现代施工中常见而重要的组成之一,结合义乌商城大道隧道工程项目,通过事故树分析法全面辨识施工危险源,并通过风险矩阵法计算出该工程风险等级为中风险,同时对已发生的典型基坑工程事故进行分析,借鉴事故经验,针对该工程项目的危险源提出了应对措施,做好施工安全管理工作,确保项目施工稳步推进。

Foundation pit engineering is one of the common and important components in modern construction.Based on YiwuShangcheng Avenue TunnelProject,this paper comprehensively identifies the construction hazard sources through the fault tree analysis method,and calculates the risk level of the project as medium risk by the risk matrix method.Meanwhile,the typical accidents of foundation pit engineering that have occurred are analyzed and the accident experience is used for reference.In view of hazardsof the project,the corresponding measures are put forward,and the construction safety management is well done to ensure the steady progress of the project construction.
