| 摘 要： | 某水电站右岸软弱岩带发育，坝基岩体质量较差。采用FLAC^3D分析表明，在大坝荷载或大坝＋库水荷载作用下，右坝基（肩）变形总量及其与左坝肩变形差异均较小，右坝肩变形随时步衰减较快。结合坝基地质条件分析，右岸软弱岩带不会导致坝肩变形失稳。

| Abstract: | There are many weak fractured zones and net-cracks inside a right damabutment at a hydro-electrical power station.In order to evaluate their influences to deformation and stability of the right dam-abutment,the method of FLAC~(3D)(Vision 2.0) study is carried out on the basis of analysis on the geological conditions.It is shown that total deformation of the right dam-abutment is small, and the differential deformation between two dam-abutments is also small.The deformation of the right dam-abutment decreases rapidly as time-step under rock-fill dam load or dam and reservoir load.There is no obvious influence of the weak fractured zones on deformation and stability of a right dam-abutment. |
