基于信息量法-层次分析法的花岗岩斜坡带地质灾害风险评价
Risk Assessment of Geological Disasters in Granite Slope Zone Based on Information Method and Analytic Hierarchy Process:A Case Study of Tengchong City,Yunnan Province
摘要
Abstract
The granite is a kind of special stratum constructed by magmatic rock.When weathered,the rock mass is hard and dense,and the mechanical strength is high,but the weathering resistance is poor.After weathering,its physical and mechanical strength is low,and the geological structure is more complex.Under the factors of earth-quake,rainfall and artificial activity,geological disasters are more developed.Tengchong City is located in the southwest of Gaoligong Mountain.Granite is widely distributed in this area.Based on the refined survey data of ge-ological disasters in Tengchong City from 2016 to 2022,based on the ArcGIS platform,the risk assessment system suitable for the widely distributed area of granite is constructed by using the combination of analytic hierarchy process and information method,and the risk zoning and distribution of geological disasters in this area are obtained.关键词
