摘　　要：库水位骤降时边坡稳定性对确保水库工程的正常运行十分重要。以某堆积体边坡为研究对象,根据地质资料给出的材料参数范围,对天然工况和暴雨工况下该边坡的最危险搜索滑带进行参数反演,综合选定合理的材料参数,进而通过极限平衡法分析了堆积体边坡在库水位骤降时的稳定性,验证了边坡在上述工况下的不利性,并提出了合理可行的治理加固措施。Slope stability with sudden drawdown of reservoir water level is very important to ensure the safety operation of reservoir project. Taking a stacked slope as research object, according to the material parameter range given by geological data, the most dangerous sliding zone＇s parameter inversion is implemented under the natural condition and rain storm condition. And reasonable material parameter is selected. Then the stacked slope stability under the condition of sudden drawdown of reservoir water level is analyzed by using limit equilibrium method. At the same time, the proposed method is verified. Finally, reasonable reinforcement measures are put forward.
