基于GIS与数值模拟的边坡稳定性评价
摘要:基于GIS的区域边坡稳定性定性评价和分区与基于极限平衡法或数值模拟的单体边坡稳定性定量评价是当前边坡稳定性研究的两个主要方向。在总结当前这两个研究方向结合点的基础上,基于ArcGIS和FLAC2D软件,结合编程技术将两者集成,实现了剖面自动生成和FLAC2D计算数据前处理功能。将此应用于某工程实例,进行边坡稳定性定性和定量评价,结果客观准确。
Abstract:There are two main research directions in the field of slope stability evaluation. One is slope stability qualitative evaluation and zoning based on GIS, the other is single slope stability quantitive evaluation based on limit equilibrium method or numerical simulation method. The combination points of the present two research directions are summarized. The functions such as profile automatic generation and preprocessing of FLAC-2D simulation data are realized based on integrating of ArcGIS and FLAC-2D by program developing technique. A case study of certain project is presented to test the reliability of the model, including slope stability qualitative and quantitive evaluations. The result is objective and accurate.
