| 摘 要： | 针对三维边坡极限平衡分析中滑体构造复杂困难的问题,提出了基于离散条柱的三维滑体构造方法。该法将坡体离散成条柱,利用离散点处坡面高程和滑裂面高程判断条柱是否有效,再通过种子填充算法搜索出构成坡体的离散条柱,最后根据坡体的边界条柱求解近似滑坡周界。方法较简便并具有良好的通用性。

| Abstract: | Three-dimensional landslide construction method based on discrete column is put forward according to the problems of complicated and difficult landslide structure during three-dimensional slope ultimate equilibrium analysis.In this method,slope is dispersed into columns.The validity of columns is judged with slope elevation and sliding face elevation at the location of discrete point.Then,discrete columns composing slope are searched through seed fill algorithm.Finally,the solution of approximate landslide ... |
