| 摘 要： | 介绍对边坡稳定分析三维极限平衡方法的一个新解法 ,它是二维Spencer法在三维条件下的扩展。该法保证了滑坡体三个方向的静力平衡 ,同时 ,还增加了一个整体力矩平衡条件 ,行界面的条间力不再假定为水平 ,条底的剪力方向也不假定为平行于主滑平面。考题和工程实例说明了其可行性和实用性。

| Abstract: | This paper describes an approach to three dimensional slope stability analysis.It is an extension of the 2 D Spencer's.The new method allows the static equilibrium in all the three directions of the failure mass,with an additional condition satisfying the requirement for moment equilibrium.The number of assumptions made for the inter column forces has been reduced,compared to the other 3 D methods commonly used.This paper describes the results of some illustrative examples and applications in a number of engineering projects. |
