复杂地质条件下隧道施工风险管理

Tunnel Construction Risk Management Under Complex Geological Conditions

鉴于山岭隧道修建时复杂的地质及周边环境,针对多种地质因素影响下的隧道施工风险管理进行研究,基于WBS-RBS理论,对复杂条件下隧道施工风险因素进行识别,将熵权系数与隶属梯度矩阵相结合,建立具有代表性的山岭隧道动态施工安全风险管理模型。并以山岭某隧道为依托,利用WBS-RBS耦合矩阵和动态施工管理模型对该隧道进行动态分析控制,结合该隧道溶洞段施工风险等级给出了对应的防治措施。

In view of the complex geological and surrounding environment of mountain tunnel construction,the tunnel construction risk management under the influence of various geological factors was studied.Based on the WBS-RBS theory,the tunnel construction risk factors under complex conditions were identified,and the entropy weight coefficient was combined with the membership gradient matrix to establish a representative mountain tunnel dynamic construction safety risk management model.Based on a tunnel in mountain,WBS-RBS coupling matrix and dynamic construction management model are used to carry out dynamic analysis and control of the tunnel,and corresponding prevention measures are given in combination with the construction risk level of the tunnel cave section.
