边坡的工程稳定状态取决于影响边坡稳定性的各种因素,其中边坡的赋存环境-地下水对边坡稳定性有重要影响[8]。为了研究库水位上涨过程中库岸稳定性的变化,本文结合某库岸边坡工程,利用有限元分析软件-GEO-SLOPE及SEEP/W耦合模拟库水位以不同速率上涨过程中库岸的稳定性变化。结果表明:随着库水位升高,库岸稳定性先小幅降低后升高;和库水位缓慢上涨相比,快速上涨前期稳定性差,后期稳定性明显要好。
The stability of the slope depends on various factors that affect the stability of the slope. The occurrence of the slope-groundwater has an important influence on the stability of the slope [8]. In order to study the change of reservoir bank stability during the rise of reservoir water level, this paper combined with the engineering of a bank slope, simulates the stability of reservoir bank with different rates of rise by the combination of GEO-SLOPE and SEEP / W finite element analysis software Sexual change. The results show that as the water level of the reservoir increases, the stability of the bank first decreases slightly and then increases. Compared with the slow rise of the water level of the reservoir, the stability of the rapid rise is poor and the stability at the later stage is obviously better.
