There are complicated hydrogeology problems such as a large quantity of inflow water and a great of dynamic changes during construction of the tunnel in Wuzhi mountain. These jobs were presented in this paper in details such as surveying geological environment of the tunnel area, analyzing track characteristics of groundwater and contrasting hydrochemistry characteristics of groundwater in different periods. And the hydrodynamic zones at the tunnel were also analyzed. Results show that the inflow water is circulating groundwater in the deep earth. The inflow water at the entrance of the tunnel is from the sandy shale region. And the inflow water at the exit of the tunnel is mainly composed of gypsum-dissolved water. The results also show that there are direct relation between the tunnel inflow water and the groundwater on the earth’s surface proved by the composition of samples of sulfur and oxygen isotopes. The difference of the water-bearing zone in the isolated groundwater was disposed when the tunnel was exploited. And the transverse water-bearing zones were connected by the one at the earth’s surface.
