| 摘 要： | 运用Bishop与强度折减法,研究了库水位缓慢下降、骤降、骤升变化时对某滑坡稳定性的影响,得到在库水位骤降或骤升时,滑坡安全系数均小于水位缓慢下降时的安全系数,且水位约达到坡体高度的0.3时稳定性最小的结论.

| Abstract: | It using Bishop and strength reduction ways get the influence of water level slow decrease,rapid decrease and water level rapid rise to the stability of the slope.The factors of safety of the slop in the conditions of water levels rapid rise and rapid decrease are both less than that in the condition of water level slow change and it gets the minimal value when the ratio of water level-height to the slop-height from the base gets 0.3. |

| Keywords: | slope strength reduction ways factor of safety water level change velocity stability |
