%X A 3D finite element model including 41 large structures and 5 faults based on the real geometry is established. The model is used to study the stability of 3# dam foundation of the left power house of the Three Georges Project and the failure mode of power house. A rule for estimating safety factor of dam foundation in terms of strength reservation is proposed based on the results of the 3D finite element analyses. For 3# dam foundation,the suggested safety factor is about 3.5 based on the computation results,which also confirms the safety of power house.
