Abstract: In the seepage control analysis, many drainage simulation methods have developed, such as drainage substructure method, expansion flow resistance method, etc. However, there are many complicated drainage needed in large underground cavities, and it is miscellaneous for simulating each drainage hole in all. This paper illustrates the simplified method with underground cavities on the left bank slope of Nuozhadu Hydro-project. Base on the reasonable premise for flux boundary and head boundary, by comparison with several schemes, accordant head and flux in the drainage location was reached. The resulted drainage effect achieved is reliable. It is helpful to optimize the seepage-control schemes, at the same time water-load is provided reliably for the evaluation of deformation and stability.

Key words: seepage flow, 3-D FEM, hydrogeology
