摘要
该文在现有的边坡稳定性三维极限平衡法分析的基础上,提出了一种评价边坡稳定性的三维极限平衡方法,它是二维Spencer法在三维条件下的扩展。该方法考虑了条间作用力和底滑面剪切力方向对边坡稳定性的影响,通过滑坡体三个方向的静力平衡,推导出边坡稳定安全系数的计算公式。
Based on the published 3D limit equilibirum analysis methods,a new method is presented for stability evaluation of slope.The 3D limit equilibirum method is actually an extension of the Spencer Method in 2D.The inter-slice forces and the direction of shear force on the sliding surface are taken into account in the new method.It allows the static equilibirum in all three directions of the failure mass and works out the formula 3D factors of satefy.
