Abstract: Seepage analysis of a hydropower station is extremely important in design stage; however realistic results is difficult to obtain for the comlexity of the seepage situation. A comprehensive exposition of the seepage analysis process is given based on Aqing hydropower station. Contents including the familiar with the project overview and hydrogeological conditions, a clear analysis of the task, the model generalization and mesh generation, the selection of material parameters, the selection of computing solutions and the determination of boundary conditions, the result analysis, scheme comparison, parameters sensitivity analysis, are introduced step by step. To well done each step makes great sense to fully understand the real seepage situation in the engineering project and a reasonable design for anti-seepage and drainage system. It is not necessarily that the discharge of the greatest section of the dam will be greater than that of sections at the bank. The total discharge may also greater than the product of the length of the dam axis with the discharge at the greatest dam section.

Key words: hydropower station, finite elements, seepage analysis, seepage control
