基于DEM边坡强度折减分析

Slope strength reduction investigation based on DEM

基于传统的强度折减理论,探讨了离散元背景下的强度折减理论,并用FLAC软件进行验证。结果表明:采用本文的强度折减方法与传统的强度折减理论得到的边坡安全系数、边坡位移、滑体滑裂面位置和形状基本一致,表明本文的强度折减方法具有一定的合理性与科学性。

Based on the strength reduction theory,the strength reduction theory of the discrete element is discussed,and the FLAC software is used to verify the theory. The results show that the strength of this reduction by using the strength reduction method and traditional reduction theory obtains the safety coefficient of slope,slope displacement,landslide sliding position and shape of the basic agreement,which shows that the strength reduction method has certain rationality and scientific nature.
