摘　　要：在研究Sarma法原理及其应用的基础上,针对库区蓄水后边坡的特点对传统的Sarma法做了改进。巧妙地将浮力应用在改进中,并将改进成果应用到某水电站左岸边坡倾倒蠕变岩体的稳定性评价中,简化了计算过程,取得满意的结果。Based on researching the principle and application of Sarma method, the traditional Sarma method has been improved considering the reservoir region slopes＇ characteristic after storing water. Floatage is smartly added in calculation. Finally, the improved method has been applied to evaluating the stability of a creeping rocky slope at the left bank of Longtan Hydropower Station in China.
