等厚抛石护坡时土坡临界坡度的判定

本文系根据Fellenius的土坡稳定理论分析的基本假设为基础,即假设土坡滑动曲面为圆弧面,并简化为平面问题,用静力平衡方法,按照土坡的主要特征条件,引入土坡临界坡度的概念,推求等厚抛石护坡适用与否的简易判别计算式。

Estimation of Critical Sloping Ratio of Soil Slope Pretected by Isopachous Riprap

This paper is based on the fundmental hypothesis about stability analysis of soilslope proposed by Fellenius. It is assumed that the sliding surface of soil a circular surface, andalso the model is reduced as a plane problem. Here, paper develops the concept of critical slopeof soil slope, considers primary factors and conditions of soil sliope, by use of static equiblibriummethod, a simple and easy formulas available for estimating soil slope to be reliable or not is de-rived.
