广西大部分地区属典型的喀斯特地貌,地下河发育。本文以西南岩溶地区某高速公路隧道穿越地下河为例,分析岩溶地下水动态特征及计算推测最大洪水位标高,提出几条经济可行的治理隧道水患的措施。
Most of Guangxi is a typical karst landform, underground river development. In this paper, an expressway tunnel crossing the underground river in the karst area of Southwest China is taken as an example to analyze the dynamic characteristics of karst groundwater and to calculate the maximum flood elevation. Some feasible and feasible measures to control tunnel flooding are proposed.
