摘要

为了研究库水位下降速度、库水位下降时间和渗透系数对边坡稳定性的影响，本文结合某工程，利用现有的程序对多种方案进行了模拟。结果表明：库水位下降速度越大，滑弧的深度越大，比较容易发生深层滑动。边坡的安全系数分别随着库水位高程的减小和库水位下降时间的增加均出现先减小后增加的趋势。不同的库水位下降速度有不同的临界库水位和临界下降时间。渗透系数对边坡的稳定性影响较大，渗透系数越大，越有利于边坡的稳定。

Abstract

In order to study the influence on slope stability produced by the coefficient of conductivity

descendent speed and time of reservoir’s water level

combined with a certain project

the numerical simulation of many schemes has been done. It is shown that the depth of the slip arc becomes bigger and the appearance of deep slide becomes easier with the bigger descendent speed of reservoir’s water level. The tendency of slope’s safety factor first becomes decrescent and then increscent with the decrease of the reservoir water level and the increase of the persistence of time. The critical reservoir’s water level and critical persistence of time are different for different decrescent speeds of water level. The bigger the influence on the stability of the slope produced by the coefficient of conductivity and the bigger of coefficient of conductivity

the better to the stability of the slope.
