3D Computational Modeling and Stability Analysis of Highway Slope: A Case Study from the X104 Section in Ganxian County

Highway planning requires geological surveys and stability analysis of the surrounding area. In the early stage of the survey, the modeling and stability analysis of the survey area can be carried out by using GIS software to intuitively understand the topography of the study area. The use of DEM to extract terrain factors can be used for simple stability analysis and the source data is easy to obtain, simple to operate, fast to analyze, and reliable analysis results. In this paper, taking the X104 road section in Ganxian County as an example, the ArcGIS platform is used to carry out 3D modeling visualization and stability analysis, and the stability evaluation map of the study area is obtained.
