摘要

基于Petrel软件实现的三维地质模型

提出了一种考虑整体滑动的三维极限平衡新方法。假设各块段重心点作用在一条直线上且与主滑方向一致

利用三维地质模型得到的滑动面表面积、滑体体积以及重心点处滑面切线角度

在忽略块段间竖向切力的情况下

建立了土质边坡力的多边形闭合和极限平衡条件的稳定性分析方法。通过经典算例的验证

该方法计算简单

具有很好的可行性和实用性。

Abstract

This paper presents a new theory of 3D limit equilibrium based on the 3D geological model built by Petrel.On the assumption that centers of gravity of the blocks are in a straight line and consistent with the main sliding direction.The sliding surface area

landslide volume and center of gravity sliding cutting angle are determined by the model.The stability analysis method of soil slope is established through ignoring the vertical shear between the blocks.This method is simple and practical

and is proved by the classic example.
