摘　　要：结合双鸡沟边坡两种不同滑动破坏模式,基于三维Spencer法运用3D-SLOPE软件对边坡稳定进行分析计算。针对边坡变形体,分别拟定了八种计算工况,根据三维极限平衡分析,得到两种滑动模式在不同工况下,仅有一种滑动模式库水骤降时的边坡稳定性不能满足规范要求,其余均能满足规范要求,可以为工程实践提供依据。Combined with two different slope sliding failure modes of Shuang Ji Gou and based on3D Spencer method,the paper uses the3D-SLOPE software to analyze slope stability.In view of the slope deformation,eight kinds of calculation cases are worked out respectively.According to the three dimensional limit equilibrium analysis,the two sliding modes under different conditions are obtained.However,only one kind of sliding mode can’t meet the requirement of slope stability when the reservoir water drops,the others all can meet the specification requirements.Therefore,the results above can provide the basis for engineering practice.
