摘　　要：应用三维动力有限元法对新疆叶尔羌河中游渠首工程闸室的抗震稳定性进行了分析。结果表明,前海进水闸和泄洪冲砂闸在地震工况下闸室的抗滑稳定安全系数均满足规范规定的相应容许值,其整体稳定性是有保障的。In this paper,the three-dimensional dynamic finite element method was applied to the seismic stability of the lock chamber in the middle ancient project of Xinjiang yarkant river. The results show that： The factor of safety of anti-sliding stability for the head gate and the flood discharge sluice under earthquake conditions meets the specifications stipulated,the overall stability is guaranteed.
