Abstract Due to the terrain and the complicate geological conditions，the underground powerhouse near the abutment often affects the safety and stability of dam-foundation of super high arch dam. The interaction of dam and underground powerhouse at Wudongde dam was analyzed considering the influences of the distance，the angle and the strength of rock mass. 3D nonlinear finite element analysis with Drucker-Prager yield criterion was carried out. The displacements，the stress，the arch thrust and the overall safety factors of dam and powerhouse foundation of different analysis cases were obtained for analyzing the interaction of dam and underground powerhouse. The results show that the deformation of the abutment is larger when the powerhouse is close to the dam. The dam-powerhouse interaction has little influence on the overall stability of the dam-foundation system.

Key words： hydraulic engineering super-high arch dam underground powerhouse interaction mechanism overall stability
