| 摘 要： | 基于剩余推力法提出了一种边坡稳定分析的三维方法.该法可用于计算具有任意形状滑动面的边坡在复杂荷载作用下三维稳定安全系数.首先将边坡用铅直面离散为柱条,然后采用剩余推力法的原理,基于摩尔库仑准则,根据条柱的静力平衡条件,并考虑条柱间作用力的影响,推导出边坡稳定系数.算例验证了该方法的有效性和可行性.

| Abstract: | A new approach for three-dimensional slope stability analysis is presented. The proposed method can be used in the slope stability analysis with arbitrary sliding surface. The slope is discreted into columns by vertical planes. Taking the intercolumn force functions and the static equilibrium condition along three directions into account, the safety factor of the slope is obtained on the basis of the residual thrust method and Mohr-Coulomb criterion. The validity and feasibility of the method are verified by the numerical example. |
