摘要
以二蛮山滑坡为例,利用FLAC3D再现降雨滑坡过程求解安全系数,并对边坡稳定性分析评价,与ArcGIS软件研发的新控件得出直观的滑坡预警图对比。结果表明:基于ArcGIS软件得出研究区域危险区划评价图,与滑坡的宏观地质现象均具有较高地吻合度。
Erman mountain landslide as the object of study, we used FLAC3D to simulate rainfall landslide process to solve the safety factor, and compared with the new developed control of ArcGIS to obtain intuitive landslide warning graphs. Results show that risk zoning evaluation chart of research area based on ArcGIS and the macroscopic geological phenomenon of slide have goodness of fit.
