通过建立某一边坡的数值模型,分析了不同工况下边坡的稳定性。结果表明:降雨条件下无支护边坡的剪应变增量和竖直向位移较大,草本植被护坡边坡及采用锚杆和草本植被护坡相结合的边坡剪应变增量和竖直向位移依次减小。无支护边坡及草本植被护坡的边坡安全系数较小,降雨作用后采用锚杆和草本植被护坡相结合的边坡依然处于稳定状态。
By establishing a numerical model of a slope, the stability of the slope under different conditions is analyzed. The results show that the increment of shear strain and the vertical displacement of unsupported slope are larger under the condition of rainfall. The slope shear stress increment of the slope of the vegetation revetment and the combination of the bolt and the herbaceous revetment slope and the vertical Displacement in turn decreases. The slope safety factor of unsupported slope and herbaceous slope is small, and the slope combined with bolt and herbaceous slope after rainfall is still in steady state.
