Abstract Research purposes:The geological conditions are complex in the area of the Jinping second level power station and there are four tunnels with 17km length，extreme burial － depth and large diameter．A simplified seepage model is established with FEM for the surrounding rock mass of tunnels in order to mainly research the seepage characteristics of the tunnel under the different conditions．

Research conclusions:The results show that the seepage characteristics is less influencd by grouting circle thickness and permeability under different conditions，and the seepage pressure of surrounding rock mass increases significantly beacause of the blocking the drainage tunnels and the auxiliary holes of the A and B lines during operation period．The results can be as the reference basis for the design and construction of Jinping deep buried tunnel for the second level power station．

Key words： the Jinping second level power station deep buried tunnels seepage characteristics seepage control effect
