本论文以天台乡滑坡为研究对象,在降雨条件下从软岩流变的角度去研究滑坡的形成过程,即研究滑坡是如何从蠕滑到整个滑面的形成,再到其发生的过程。采用Flac3D有限元软件模拟斜坡体在天然状态与降雨情况下的应力变化、应变变化、以及位移变化情况,从而将滑坡的外部触发因素和内在物质原因结合起来对上述缓倾角滑坡的启滑机制进行全面解释。
This paper takes Tiantai Landslide as the research object, studies the formation process of landslides from the perspective of soft rock rheology under the condition of rainfall, that is, studies how the landslide is formed from creep to the slip surface and then to the process of its occurrence. The Flac3D finite element software is used to simulate the stress changes, strain changes and displacement changes of the slope body under the condition of natural and rainfall, so that the external triggering factors of the landslide and the intrinsic material causes are combined to make the slip mechanism of the above gentle dip landslide Comprehensive explanation.
