多层次模糊综合评价法在复杂岩溶隧道施工安全风险评估中的应用

Application of multi-level fuzzy comprehensive evaluation method in the safety risk assessment of complex karst tunnel construction

山区高速公路岩溶隧道地质条件复杂,对施工技术和设备要求高,工程施工环境风险大,风险等级高且随施工进度动态变化,导致施工风险防控难度大。以张桑高速建设项目为例,基于多层次模糊综合评价法对该项目黄香湾隧道岩溶区段的重大风险源开展施工安全动态风险评估,并提出有针对性的控制措施,实现风险的分级管控。同时,为其他复杂岩溶隧道风险评估提供参考。

The geological conditions of karst tunnel in mountainous expressway are complex,the construction technology and equipment requirements are high,the construction environment is risky,the risk level is high and dynamically changes with the construction progress,leading to the difficulty of construction risk prevention and control.Taking the construction project of Zhang-Sang Expressway as an example,based on the multi-level fuzzy comprehensive evaluation method,the dynamic risk assessment of construction safety was carried out for the major risk source in the karst section of the Huangxiangwan Tunnel of the project,and targeted control measures were proposed to achieve hierarchical risk management and control.At the same time,it provides reference for risk assessment of other complex karst tunnels.
