Application of Information Method Based on MapGIS in Transmission Line Engineering
The geological conditions of the southwest mountainous area are complex,with varied topography,diverse stratigraphic lithology and strong tectonic action.In order to further improve the accuracy of analysis and evaluation of engineering geological conditions in potential route,taking a 500kV ultra-high voltage transmission line project in Yunnan Province as an example,and uses MAPGIS platform to quantify the influencing factors,including topographic and geomorphic conditions,geological structure,disaster,lithology,and human activities.The mathematical model is established by information method,the classification standard is determined,and the engineering geological zoning map is drawn,which provides quantitative basis for route selection and optimization.
