上海市漕宝路快速路盾构隧道工程风险管理分析及控制

Risk Management Analysis and Control of Caobao Road Expressway Shield Tunnel Project in Shanghai

摘要:

上海市漕宝路快速路项目工程规模宏大、建设条件异常复杂。为降低漕宝路15 m超大直径长距离盾构隧道工程的施工风险，从定性及定量角度分别对工程水文地质风险、盾构隧道本体风险及环境风险三类风险源进行辨识、分析及计算评估，制定一套有效评估盾构隧道工程整体风险的表格及风险等级划分标准，以评估其安全风险等级。根据盾构隧道工程安全风险等级评定结果，结合工程特点提出针对性风险管理控制措施，保障盾构隧道顺利掘进，可为今后类似大型复杂盾构隧道工程项目风险管理及控制提供借鉴。

Abstract:

The Shanghai Caobao Road Expressway Project is of grand scale and has extremely complex construction conditions. In order to reduce the construction risk of the 15-m ultra-large diameter long-distance shield tunnel project of Caobao Road, three types of risk sources including hydrogeological risk, shield tunnel origin risk, and environmental risk are identified, analyzed, calculated and evaluated from both qualitative and quantitative perspectives. A set of forms and risk level classification standards for effectively assessing the overall risk of shield tunnel projects is formulated to evaluate the safety risk levels. Based on the safety risk level assessment results of shield tunnel project and combined with the characteristics of the project, the targeted risk management and control measures are proposed to ensure the successful shield tunneling, which can provide reference for risk management and control of similar large-sized complex shield tunnel engineering projects in the future.
