基于反算原理的滑坡推力简易估算

滑坡滑面的抗剪强度指标往往用反算法确定。分析表明,对已变形位移的滑坡,其推力可不反算滑面抗剪强度指标而直接按现状稳定系数和设计安全系数简易地估算,一般地,滑坡推力等于下滑分力乘以设计安全系数相对于现状稳定系数的提高比例值。进而讨论了其对不同设计工况、各种典型形状滑面的适用条件。这是一条估算滑坡推力的捷径。

An Easy Estimation of Landslide Sliding Force Based on Back Calculation Principle

Shearing strength parameters of slide surface are often determined by "back calculation method".Analysis shows that,for the landslide of situated deformation condition,its sliding force can directly be estimated based on stability coefficient in present and safety coefficient in design.The sliding force equals to the product of distributive downslide force and the relative ratio between the stability and safety coefficients.Further,the suit conditions of the method in every design environments and every typical slide surface shapes are discussed.This is a simple method of estimating landslide slide force.
