通海隧道是中国云南国际铁路通道昆明-河口线上的主要工程,也是云南省在建的最长隧道。隧道全长10302 m,全隧道为单面坡,最大坡度为20.4‰。该隧道在通海县境邻近杞麓湖,作为通海县重要的水资源,杞麓湖具有工农业用水、调蓄、防洪、航运、旅游、水产养殖等功能,是通海县社会经济发展的主体。隧道施工以来,在进出口的数个出水点涌出大量的地下水,由于工程区为生态敏感的岩溶地区,因此亟需查明隧道涌水与周边杞麓湖等水体的水力联系。通过对隧址区岩溶水文地质条件的研究,在充分了解区域构造环境、褶皱与断裂特征、掌握地下水含水岩组及其富水特性、地下水补径排特征的基础上,划分出隧址区的水文地质单元,结合隧道施工涌水状况以及已开挖段所揭示的地质条件等,利用地质原形研究和同位素分析等方法重点分析隧道涌水来源及其与杞麓湖的水力联系,明确隧道工程对周边地区水环境的影响。

Tonghai tunnel is 10.302 km long, which is a super long tunnel on the Kunming-Hekou international railway now under construction. As the tunnel is near by the Qilu Lake, which is the main water source of Tonghai Country, thus the detection of the hydraulic connection between the tunnel and Qilu lake is essential. This paper outlines karst hydro-geologic conditions and the investigation of the regional tectonic environment, folds and fractures, main aquifers and their water-rich characteristics, underground water recharge, runoff, and drainage conditions plus the hydro-geologic units of the tunnel area. Combined with gushing water conditions in tunnel construction process and geological condition in excavated sections, the source of gushing water and its hydraulic connection with Qilu Lake has been detected, the environmental impact of gushing water has been analyzed.
