Study on AHP-Based Comprehensive Evaluation Method of Earthquake-induced Geological Hazard
Based on AHP theory,the factors affecting earthquake-induced geological hazards,including collapses,landslides,debris flows,soil liquefaction,and soft soil seismic subsidence,were identified,and a comprehensive evaluation method with convenient and suitable advantages was established.The parameters of the system can be easily obtained.First,based on existing seismogeological data,the classification of earthquake-induced geological hazards for single factors is provided.Second,the contribution weight of each factor is determined using AHP.Finally,using the data processing tools of ArcGIS,the classifications of earthquake-induced geological hazards for all factors were superimposed,and a comprehensive evaluation classification was derived.Taking Pingwu county in Sichuan province as an example,a classified zonation map of earthquake-induced geological hazards was produced based on existing geological and geographical data.This map can serve as a reference for regional planning and emergency rescue operations after an earthquake.
