岩溶问题成为我国南方一些地区隧道施工中的一大难题。在岩溶发育地区,必须在施工前进行有效的超前地质勘察,合理选线。在施工过程中,正确处理突水突泥问题,对不同类别的溶洞选取最为正确有效的处治措施。施工阶段结束后,还需要对渗水量以及隧道围岩变形进行跟踪监测。建立完善的施工方案,是保证施工质量和人员设备安全的重要前提。
Karst problem has become a major problem in tunnel construction in some areas in southern China. In karst development areas, it is necessary to conduct effective advance geological exploration and reasonable route selection before construction. In the process of construction, it is proper to deal with the problem of water inrush and mud and select the most correct and effective treatment measures for different types of karst caves. After the completion of the construction phase, it is also necessary to track and monitor the water seepage and the deformation of the surrounding rock of the tunnel. The establishment of a sound construction program is to ensure the construction quality and safety of personnel and equipment an important prerequisite.
