岩溶区高速公路隧道渗漏水原因分析及处治

Cause Analysis and Treatment Measures for Water Leakage in Highway Tunnel of Karst Area

渗漏水是隧道工程最常见的病害之一,严重威胁着隧道衬砌结构和行车安全。与非岩溶区相比,岩溶区隧道的渗漏水表现出特有的病害特征,且更为严重。结合岩溶区六寨至河池高速公路隧道渗漏水处治工程,针对该工程中出现的几种渗漏水形式,在总结前人技术成果的基础上,结合该项目特有的地质环境,提出了相应的处治方案,收到了良好效果。

Water leakage is one of the most common diseases in tunnel engineering, which seriously threatens tunnel lining structure and traffic safety. Compared with the non-karst area, the seepage water in the karst tunnel shows peculiar disease characteristics and more serious. Combining with the Liuzhai to Hechi Highway tunnel leakage treatment works in the karst area, summarization of technological achievements and project-specific geological environment, in terms of several forms of water leakage of the project, the corresponding treatment plan is put forwards and received good effects.
