摘　　要：人类工程活动和降水作用是多数滑坡变形破坏的主要影响因素。本文以广西环江县某滑坡为例,分析人工切坡和降水耦合作用下斜坡变形破坏的机理。研究结果表明:在人工切坡和降水耦合作用下,斜坡最开始变形破坏部位往往是人工切坡的坡脚,变形破坏呈现间歇性,变形破坏的周期和程度与降水强度和持续时间正相关。Human engineering activities and precipitation are the main factors of deformation and damage of most landslides.This paper takes a landslide in Huanjiang County as an example to analyze the mechanism of slope deformation and damage under the coupling effect of artificial cutting slope and precipitation.The results show that under the coupling effect of artificial cutting slope and precipitation,the initial deformation and damage part of the slope is often the foot of the artificial cutting slope,and the deformation and damage are intermittent,and the period and degree of deformation and damage are positively correlated with the intensity and duration of precipitation.
