An Improved Evaluation Method for Geological Hazard Susceptibility Based on Analytic Hierarchy Process

Abstract

The invention discloses an improved evaluation method for geological disaster susceptibility based on analytic hierarchy process, comprising: step 1: collecting geological basic data of the area to be evaluated, and obtaining geological disaster data of the area to be evaluated; step 2: collecting based on step 1 and the obtained data, analyze the distribution law of geological hazards in this area and the controlling factors, obtain the influencing factors controlling the development of geological hazards in this area, and obtain the influence of similar but different levels of linear influencing factors on geological hazards; step 3 : Based on the obtained influencing factors controlling the development of geological hazards in this region and the influence of different levels of linear influencing factors on geological hazards, the evaluation results of geological hazards in this region are obtained by using AHP; the susceptibility of geological hazards based on AHP The evaluation process has been improved, and the linear impact factors have been graded. This method is logical and feasible, and the evaluation results are more reasonable and accurate.

Description

technical field [0001] The invention relates to the field of geological disaster research, in particular to an improved evaluation method for geological disaster susceptibility based on analytic hierarchy process. Background technique [0002] Generally speaking, geological disasters mainly include collapses, landslides, unstable slopes and debris flows. my country is a country where geological disasters occur frequently, especially in the western region where the geological environment conditions are extremely complex. Geological disasters have caused huge losses. The evaluation of geological disaster susceptibility is to study the possibility of geological disasters occurring in a certain area, and usually adopts high, medium, low, and rare levels for evaluation. Carrying out research on the susceptibility of geological disasters can provide an important basis for the planning of regional urban construction land use, site selection of engineering projects, and formulation...
