| 摘 要： | 在地形、岩体结构、坡度、岩层倾角以及河流的作用下,澜沧江某水电站边坡已明显变形。鉴于边坡开挖后可能出现大变形问题,使用三维离散元数值计算软件建立相应的计算模型,对边坡开挖后的位移变形特征进行计算分析。结果表明,边坡开挖后浅表层岩体变形位移较大,可能产生剪切滑移破坏,对边坡稳定不利。

| Abstract: | The toppling deformation has occurred under the action of terrain,rock structure,slope,rock dip and the stream.Three-dimensional discrete element software is used to establish appropriate calculation methods for analyzing the characteristics of large deformation that may arise after the slope excavation.The results show that a large deformation may occur at the shallow part of the excavated slope and the deformation may lead to shear-slipping failure unfavorable to slope stability. |
