摘　　要：某水电站边坡工程规模大,工程技术条件复杂,自然谷坡高陡,岩性多样,并发育有断层等,场地地质条件复杂,工程边坡的安全稳定性问题十分突出。选取安全稳定问题最为突出的溢洪道进口及泄洪放空洞出口边坡典型剖面,基于Slide软件,采用极限平衡法计算边坡在正常运行、降雨及地震3种工况下的稳定性。结果表明,溢洪道进口及泄洪放空洞出口边坡安全系数均大于规范允许的安全系数,该水电站边坡稳定性满足要求。The slope engineering of a hydropower station is large in scale and complex in engineering technical conditions.The natural valley slopes are high and steep,with various lithologies and faults developed.The site geological conditions are complex,and the safety and stability of the engineering slope is very prominent.In this paper,the typical sections of the slope at the entrance of the spillway and the exit of the spillway are selected with the most prominent safety and stability problems.Based on the Slide software,the limit equilibrium method is used to calculate the stability of the slope under three conditions of normal operation,rainfall and earthquake.The calculation results show that the safety factor of the slope at the entrance of the spillway and the exit of the spillway is greater than the safety factor allowed by the code,and the slope stability of the hydropower station meets the requirements.
