Geological Hazard Characteristics And Risk Assessment Of Yunnan Xundian Jinke First-class Highway Construction Project

With the rapid development of our economy,the size of the city keeps getting bigger.Traffic conditions have become arteries of economic and Urban Development?Accelerating Highway Construction to Promote Local Economic Development?During the construction of the first class highway,Identification of the type,developmental characteristics and influencing factors of geological hazards along the route,A comprehensive assessment of geological hazards is also made,To ensure the safety of highway construction,The steady development of highways has become an important topic in urban Geological environment research.This article is based on the project of the first grade highway project of Kedu,Identification of geological environment conditions such as geomorphology,stratigraphic lithology,Geological structure,hydrogeology,engineering geology,etc.around highways and the influence mode and intensity of human engineering activities on Geological environment,On the basis of the current situation research and forecast research,Comprehensive zoning study according to section characteristics,Propose measures and recommendations for the prevention and treatment of geological hazards.A total of 5 landslides,4 collapses and 7 unstable slopes were found in the research area,Statistical analysis of these Geological hazards,Variations in geological and environmental conditions,Geological hazard development,Proposed project specifications,Types and degree of disturbance of engineering construction to Geological environment conditions,Potential for induction or exposure to Geological hazards,Impact on surrounding settlements,etc..According to the principle of similarity in the region and regional differences,A comprehensive assessment of geological hazard risk in the study area was made by using AHP.Finally,the geological hazards of the line crossing area of the research area are divided into 3 levels and 11 sections.4 sections of Gaoyi District,3 sections of Medium Yi District and 4 sections of Low Yi District.Using Mapgis software to map the risk assessment zones of geological hazards in the study area.The results can provide reference for project construction.
