摘要
针对城市建设发展中出现的潜在斜坡变形预测问题,以某潜在滑坡为研究对象,采用显式拉格朗日算法和混合-离散分区分析方法,通过Rhino和FLAC3D协同建立三维数值计算模型,对边坡开挖前后边坡破坏情况进行对比分析,预测发生区域。结果显示,潜在滑坡前缘开挖处塑性区很大,可见开挖后滑坡变形较大,潜在滑坡变形区域主要集中在其右侧前缘,建议对该区域进行重点防治。
Aiming at the problem of potential slope deformation prediction in the development of urban construction,taking a potential landslide as the research object,the explicit Lagrangian algorithm and hybrid discrete partition analysis method are used to establish a three-dimensional numerical calculation model through rhino and FLAC3D.The slope failure before and after slope excavation is compared and analyzed,and its occurrence area is predicted.The results show that the plastic area at the excavation of the front edge of the potential landslide is large,and the landslide deformation after excavation is also large.The potential landslide deformation area is mainly located in the right front,and it is suggested to focus on prevention and control of this area.
