摘　　要：水库建成蓄水后,为满足防洪和发电的要求,水位将在最低正常水位和最高正常水位之间反复升降,库水位的变动很可能诱导库岸失稳,有必要对动态水位诱导下库岸边坡稳定性进行分析。结合苏阿皮蒂水利枢纽项目运营模式,采用极限平衡分析方法,分析不同库水位工况下右岸松散堆积体稳定性演化规律,并对避免松散堆积体在水库诱导下产生灾害提出了几点建议,为松散堆积体岸坡的稳定性分析与防护提供参考。The water level of reservoir after impoundment will fluctuate between the lowest and highest normal water levels in order to meet the requirements of flood control and power generation,which is likely to induce reservoir bank instability.Therefore,it is necessary to analyze the stability of reservoir bank slope induced by dynamic water level.The stability evolution of right reservoir bank loose accumulation slope in Souapiti Hydro Project under different water level conditions are analyzed by limit equilibrium method combining with the operation modes of Souapiti Hydro Project.Several suggestions for avoiding the instability and disasters of the accumulation slope induced by dynamic water level are proposed,which will provide references for the stability analysis and protection of loose bank slopes.
