| 摘 要： | 岩溶突水是可溶盐岩分布地区修建隧道工程面临的首要工程地质问题，开展岩溶水文地质评价是隧址区的重要工作内容之一。以重庆新屋基隧道为例，在野外岩溶地质调查基础之上，分析了隧址区岩溶水文地质特征，并对新屋基隧道水文地质条件进行了分区评价。结果表明:新屋基隧道工程中的相关洞段遭遇突涌水的可能性较大，施工前应做好处置预案，以确保施工安全。

Karst Hydrogeological District Evaluation of Xinwuji Tunnel in Chongqing |
| |
| Abstract: | Karst water inrush is the primary engineering geological problem of tunnel engineering in soluble salt rock distribution area, and karst hydrogeological assessment is one of the important works. Taking Xinwuji tunnel in Chongqing as an example, based on karst geology survey in the field, the karst hydrogeological characteristics is analyzed, and its hydrogeological condition of the tunnel is evaluated in district. The results show that some cavities and sections of Xinwuji Tunnel are more possible to undergo water inrush which should be pre-arranged and disposed before construction to ensure safe construction. |
