摘　　要：某溢流坝基深部顺河向有0°角软弱夹层,影响大坝稳定。采用有限元分析,获得了可靠的贯穿滑动面。结合安全系数及极限状态计算,对软弱带进行抗滑硐塞处理,使大坝得以稳定。The deep foundation of the overflow dam has 0° angle weak band along the river,which affects the stable of the dam.This article uses the FEM to obtain the reliabe through sliding surface.Based on the safety coefficient and the limiting condition computation,carries on anti-slides Shear Keys fills processing to the weak belt,enables the dam to be stable.

关 键 词：溢流坝 软弱夹层 三维有限元 滑动贯穿面
