重庆仰头山隧道区岩溶水系统划分与系统特征研究

Research on the Division and Characteristics of Karst Water System in Yangtoushan Tunnel Area in Chongqing

为了查明黔恩高速公路仰头山隧道隧址区岩溶水发育特征,在分析工程地质环境的基础上,将仰头山隧道岩溶水系统进行划分,并对各系统的含、隔水介质、水文地质结构、岩溶发育情况及排泄量等进行了研究,揭示了各岩溶水系统与隧道的关系及对隧道施工的影响。

In order to find out the development characteristics of karst water in Yangtoushan tunnel site area of Qianjiang--En shi Expressway, based on the analysis of the geological engineering environment, the karst water system is divided in parts and the aquifer and aquiclude medium, the hydrogeologieal structure, the karst development and excretion and so on are studied. The relationship between the karst water system and the tunnel and influence on the tunnel construction is revealed.
