摘要
我国岩溶地区分布广泛,其中以西南云、贵、桂和川、鄂、湘部分地区的岩溶最为发育。随着高速铁路的全面建设,岩溶水已成为岩溶地区隧道建设的主要地质灾害之一,且贯穿于勘察、设计、施工及后期运营维护的整个过程。文章针对这一现状,从岩溶水的垂直分带、岩溶隧道纵断面、岩溶隧道辅助坑道以及岩溶隧道岩层产状等方面进行了分析总结,提出岩溶线路前期勘察及设计需高度重视的设计要点,为后期隧道岩溶水的处理预留空间和通道,更加有效的控制铁路建设的投资和工期,同时可为岩溶隧道勘察和设计提供借鉴。
Karst areas are widely distributed in China,where the karst in Yunnan,Guizhou,Guangxin,Sichuan,Hubei and Hunan is developed well.With the construction of high-speed railways,karst-water has become one of the main geological disasters for tunnel construction in karst area,and it happened in the whole process including survey,design,construction and operation&maintenance.In this paper,it is analyzed and summarized from the vertical zoning of karst water,the profile of karst-tunnel,the auxiliary gallery of karst-tunnel to the rock formation of karst tunnel,meanwhile,feeding back to the karst route survey and design with some thoughts and subtle design points.It reserves processing space and channels for post karst-water treatment in tunnel,and makes possible of controlling investment and duration of railway construction effectively.However,this article could be useful and helpful to which person involved in the survey and design of karst tunnels.
