摘要
通过三维有限元方法研究千将坪滑坡.建立滑坡三维有限元计算模型,模拟库水位上升和降雨过程引起的千将坪滑坡变形破坏机理.对千将坪滑坡在不同工况下的计算结果进行比较分析,得出在库水位上升和降雨条件下的滑坡位移场和塑性区的变化规律,从而揭示千将坪滑坡的整体变形破坏机制.
Based on 3D finite element method,the Qianjiangping landslide is studied.A 3D finite element model is built;deformation mechanism of Qianjiangping landslide caused by reservoir impounding and rainfall can be simulated wholly.Based on calculation results of Qianjiangping landslide under different conditions,some rules of landslide on displacement field and plastic zone are achieved,so as to elicit the whole deformation mechanism of Qianjiangping landslide.
