公路隧道塌方的原因分析及其防治措施分析

Analysis of Causes and Prevention Measures of Highway Tunnel Collapse

众所周知,公路隧道是地下工程的一种类型,其地质情况的变化较大、工作面集中且施工现场环境不理想。现阶段,国内公路隧道始终将山岭隧道当做主要的形式,且在掘进施工作业的过程中要求选择使用钻爆法,为有效规避公路隧道塌方,必须采用具有针对性的防治措施。

It is well-known that highway tunnels are a type of underground engineering. The changes in geological conditions are relatively large, the working face is concentrated, and the construction site environment is not ideal. At this stage, the mountain tunnel is always regarded as the main form in the domestic highway tunnel, and the drilling and blasting method is required in the process of tunneling. In order to effectively avoid road tunnel collapse, targeted prevention and control measures must be adopted.
