上海地铁11号线关键节点工可阶段工程风险评估

Risk assessment on engineering feasibility of key events in Shanghai metro line No. 11

最大程度地减小市区地铁施工中的风险事故发生率以及事故造成的损失,已成为一个迫切需要解决的课题。根据风险评估流程,结合上海地铁11号线工程实例,对该线工可阶段关键节点的主要风险,采用专家调查法和层次分析法进行了识别和评估,最后针对关键节点的风险控制提出了一些建议。

In recent years the increasing attention have been paid to the risk accidents during construction of tunneling engineering in urban area. How to reduce the risk accidents and their losses have become an important topic. At present there is an increasing concern on risk assessment of tunneling engineering. In this paper, a general risk assessment process of tunneling engineering was proposed to the project of metro line No.11 in Shanghai. Risk accidents during construction were identified firstly, the expert investigation method and AHP method were used in risk analysis, and finally some suggestion about risk control measures were made.
