摘要
针对TBM法在输水隧洞工程施工实践中存在的风险,构建基于熵权的TBM法施工进度风险评估指标体系,评估影响TBM法施工进度的关键风险项。结果表明,高压涌水、岩爆以及卡机是影响输水隧洞工程TBM法施工进度的关键风险项。同时,针对关键风险项提出TBM法施工在遭遇高压涌水层、岩爆以及卡机风险时应采取的对策。研究可为水工隧洞工程的施工风险识别与防治提供决策依据。
Concerning the existing risks at construction of diversion tunnel engineering based on TBM construction method,the risk assessment indicator system based on entropy weight has been established,which has assessed the key risks at construction by TBM method. The result showed that high- pressure blow,rock burst and block were the key risks at construction at diversion tunnel engineering based on TBM method. In addition,the countermeasures have been explored focused on the diversion tunnel construction when encountering high- pressure blow,rock burst and block. This could provide decision making basis for risk identification and prevention at diversion tunnel construction.
