摘要:
四川宣汉县天台乡滑坡为一大型顺层滑坡.文章阐明了滑坡发育的地质环境条件及基本特征.为了评价预测滑坡体在暴雨、前缘河道疏浚开挖影响下变形的发展趋势和稳定程度,采取了FLAC-3D方法对滑坡体的变形状况进行三维数值模拟分析.结果表明,天然状态下坡体整体上是稳定的,仅前缘可能会发生局部失稳;暴雨条件下坡体发生整体失稳的可能性不大,但局部范围将极有可能发生坍塌进而发生牵引式滑坡.
Abstract:
The basic characteristic of Tiantai landslide in Xuanhan county,Sichuan province is described based on engineering geological survey carried out after landsliding.In order to get a better understanding to the deformation trend and stability state of the landslide debris under extraordinary rainstorm,FLAC3D is used to make a numerical simulation.The results show that the landslide is stable in natural state as a whole,but there appears some small-scale failure at the rear part of the landslide.Under the condition of rainstorm,the whole landslide is stable also,but in the front part of the debris,some local collapse and retrogressive sliding will occur.
