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.针对此问题,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.In the deep foundation of some overflow dam base, there has 0° angle weak band along the river, it affects the dam＇s stability. Using the finite element analysis, the reliable passing through the sliding surface is obtained. Uniting the safety coefficient with the limiting condition computation,for the weak belt anti-slides shear keys are filled to enable the dam stability.
