摘要

以抚顺西露天矿北帮边坡为例，分析了边坡变形规律和破坏机制。在弱层流变试验的基础上，建立了弱层流变力学模型。通过确定加速蠕变阶段来临的极限应变量和应变速率，建立了弱层长期强度的时间效应方程，对于不同的边坡工况进行了动态稳定性评价。分析结果表明

采取相应的治理工程之后，边坡稳定系数明显提高，为控制边坡的蠕动变形破坏发展提供了科学依据。

Abstract

Taking Fushun Strip Coal Mine Slope for example

the failure mechanism and distortion rule of the slope are analyzed. Based on the creep test of soft layer

a mechanical model of creeping was proposed. Time effect equation of long term strength was established by measuring ultimate strain and strain velocity during the creeping of soft layer. According to the equation

dynamic stability of the slope was evaluated. The results show that the stability was heightened greatly after reinforcement and drain. The model provides a method for predicting and controlling the stability of creeping slope.
