摘要
岩溶的发育和分布具有明显的区域性和不规则性,是我国西南地区隧道建设中常遇到的重大工程问题之一。本研究针对西南地区某高速公路岩溶隧道处治溶洞实例,探讨隧道穿越干溶洞的治理原则,并对溶洞顶板稳定性和岩溶治理的技术措施做了具体分析,有效地解决了隧道穿越大型干溶洞的技术问题。
The development and distribution of karst is obviously regional and irregular,which is one of the major engineering problems often encountered in tunnel construction in Southwest China.According to the example of karst tunnel treatment of a highway in southwest mountainous area,this study discusses the treatment principle of tunnel crossing dry karst cave,and makes a specific analysis on the stability of karst cave roof and the technical measures of karst treatment.In the end,the technical problem of tunnel crossing large dry karst cave is effectively solved.
