水库水位上升条件下渗透系数对顺层滑坡的稳定性分析

Analysis of stability of bedding landslide with permeability coefficient under condition of reservoir water level rising

为了分析水库水位上升对顺层库岸滑坡稳定性产生的不利影响,以某典型顺层库岸滑坡为工程背景,采用GEO-SLOPE计算软件,计算了不同渗透系数的边坡岩土体在库水位上升时的渗流场,在此渗流场基础上,对顺层滑坡的稳定性进行了数值计算,并对计算结果进行了分析,得到了顺层滑坡在库水位变化条件下的安全系数和边坡岩土体的渗透系数之间的关系,为顺层库岸滑坡的边坡稳定性分析提供了可靠依据。

In order to analyze the adverse effect of the rise of reservoir water level on the stability of bedding landslides,a geoslope bank slope was selected as the engineering background. GEO-SLOPE calculation software was used to calculate the slope permeability of different reservoirs.When the water level rises,seepage field,based on the seepage field,the stability of the bedding landslide is calculated numerically,and the calculation results are analyzed,and the safety factor and edge of the bedding landslide under the change of reservoir water level are obtained.The relationship between the permeability coefficients of slope-soil soils provides a reliable basis for the analysis of the slope stability of bedding landslides.
