中文摘要	当特高拱坝地下厂房受地形、地质条件限制,需建在坝肩较近位置时,厂房的开挖施工和长期运行常会影响坝肩安全稳定。首先以乌东德大坝为例,分析大坝与厂房布置的特点,然后从力学的角度分析大坝和地下厂房的力学和安全稳定的相互作用机制;并采用Drucker-Prager屈服准则,对大坝与厂房开展精细非线性三维有限元分析,重点研究大坝和厂房在正常荷载和超载荷载下的变形、应力、拱推力、坝肩基础、整体安全度分布以及相互作用机制,得到大坝与厂房相互影响稳定的工作状态条件。研究成果可供类似工程设计分析提供参考。; 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.
