| 摘 要： | 运用有限元软件ABAQUS,采用有限元强度折减法对含软弱夹层土坡的稳定性进行了数值模拟。主要分析在坡高、坡角、夹层埋深、夹层倾角和夹层厚度变化的五种工况下,土坡的安全系数和最大总位移。随着软夹层倾角和厚度的增大,边坡安全系数和最大总位移均呈下降趋势。

| Abstract: | The FEM software ABAQUS is applicable and the finite element shear strength reduction method is adopted for the numerical simulation of the stability of slopes with soft interlayer so as to analyze the safety factor and maximum total displacement of soil slopes under five different working conditions, including slope heights and angles, and the depth, angles and thickness of soft interlayer. The safety factor and maximum total displacement decrease with the increment in the angle and thickness of soft layer. |
