在隧道工程施工过程中,隧道塌方是一种常见的地质灾害,具有安全风险高、施工难度大、不可预见性多等特点。为了保证隧道工程的顺利开展,需要做好软弱围岩隧道塌方的处理工作。本文以实际工程为例,对隧道塌方的处理难点进行了分析,最后对大跨度软弱围岩隧道塌方的治理措施进行了分析。
In the tunnel construction process, tunnel collapse is a common geological disasters, with high security risks, construction difficulty, unpredictability and so on. In order to ensure the smooth development of the tunnel project, we need to do a good job of dealing with the landslide of the weak surrounding rock tunnel. In this paper, the actual project is taken as an example to analyze the difficulty of tunnel collapse treatment. Finally, the control measures of the tunnel collapse in the long-span soft surrounding rock are analyzed.
