- Abstract:
- 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.
