摘要
进行成贵铁路观音山隧道工时,隧道多处穿越岩溶发育地带,出现多种复杂的岩溶地质灾害,本项目对不同情况下岩溶地质灾害的治理技术及手段进行了深入的探索和研究,对隧道底部溶腔填充物创造性地采用了路基复合地基处理的加固技术。以上综合治理措施取得了良好的效果,为隧道岩溶治理提供借鉴和开创新的思路。
During the construction of the Guanyinshan Tunnel in Chenggui Railway, the tunnel passes through the karst development zone and there are many complicated karst geological disasters. The project has carried out in-depth exploration and research on the techniques and means of karst geological disasters under different conditions. The reinforcement technology of the roadbed composite foundation treatment is creatively applied to the cavity filling at the bottom of the tunnel. The above comprehensive treatment measures have achieved good results, providing reference and innovative ideas for tunnel karst management.
