摘　　要：吉林台水电站厂房后边坡开挖形成140～340m的高边坡,保证其长期运行稳定性至关重要。在结合地质资料对边坡的失稳模式进行初步判断的基础上,采用极限平衡分析方法对正常蓄水、暴雨影响、地震荷载等工况条件下边坡的整体抗滑稳定性进行分析,得出暴雨对边坡稳定影响较大的结论,据此提出以排水结合预应力锚索为主的边坡加固增稳措施,实践证明该措施是有效的。The slope behind the powerhouse of Jilintai hydropower station is about 140～340m in height. It is very important to ensure the safety of the slope for a long time. According to the geological materials and calculation result, authors estimate the stability of this high slope under some work conditions, just like impound, storm rainfall, earthquake, and so on. Then a conclusion is given that the storm rainfall is the most important factor for the stability of the slope. On the basis of the estimation conclusion, authors put forward a reinforcement design plan.
