摘　　要：对西南某河流改道导致边坡变形的破坏模式进行调查,总结边坡在坡向与岩层倾向间夹角变化条件下的变形破坏特征。采用成都理工大学开发的边坡块体稳定性分析系统(SASW),模拟计算边坡中坡向与岩层倾向在不同夹角情况下边坡楔形块体的稳定性。根据模拟分析结果,建议采用夹角40°作为岩质顺向边坡和斜向边坡的划分界限。岩质顺向边坡进一步划分为顺层顺向边坡和切层顺向边坡,并采用夹角20°作为其划分界限。A survey is made on the failure mode of slope deformation resulted from the diversion of a river in Southwest China. The stability of slope wedge-shaped blocks is calculated with the use of the slope block stability analysis system, developed by CDUT. Based on the calculations, we propose boundary determination between consequent and oblique slopes, by an angle of 40°. Consequent slope is further divided into bedding consequent slope and cutting consequent slope with an angle of 20°.
