基于极限平衡法和FLAC~(3D)的陕南地区某边坡稳定性分析

为了研究陕南地区边坡的稳定性,选取某处典型边坡进行研究。通过运用FLAC3D数值模拟软件和极限平衡方法,结合工程实际,根据极限平衡法分析典型边坡的稳定性系数,并且建立模型,进行滑坡的数值模拟,得到水平方向的位移云图和水平方向的应力云图。结果表明,该边坡的三级坡存在着滑动趋势,一二级坡体稳定,应该对该地区同类坡体采取加固措施。

Analysis of Slope Stability of Southern Shan Xi Province Based on Equilibrium Limit Method and FLAC3D Software

In order to study the slope stability of Southern Shan Xi province, the paper selects a typical area, using FLAC 3D numerical simulation software and equilibrium limit method, analysis of slope stability coefficient based on equilibrium limit method and combines the engineering practice and establishes the model to conduct the landslide numerical simulation, finally we can get displacement nephogram and horizontal stress nephogram in the horizontal direction. The result shows that there is a sliding trend on the third slope which should take some reinforcement measures in the particular area, while the first and second are stable.
