Abstract：According to the engineering geology and the hydrogeology of a certain hydropower station，a finite element model with 8 geological layers and complicated boundary condition is built. The experimental results of drilling test，the pumping well test and the injection test are collected and selected as the reference points in the process of inverse analysis. The inverse analysis result shows that it is in good agreement with the experimental result at the reference points. The permeability coefficients for each geological layer and region are obtained；and the seepage field of the whole foundation of the dam has also been calculated. All of these provide the fundamental parameters for the design of dam or further analysis to check the rationality of the engineering design.
