摘要
根据江西万载县地质环境条件及发育特征,选用了岩土体类型、控制结构面类型、岩体完整程度、坡度、坡高、灾害点密度、降雨和人类工程活动这8个因素,作为地质灾害易发性评价因子,采用层次分析法确定了各评价因子的权重,并通过专家系统法赋值,将万载县划分为地质灾害高易发区、中易发区和低易发区。此结果可为万载县的地质灾害预防和治理提供理论依据。
According to the geological Environment conditions and development feature,taking 8 factors,ie,geotechnical body type,control structure surface type,rockbody integrity degree,slope gradient,slope height,disaster spot density,raining and mankind engineering activity as the assessment factor of probability and determining the weight of assessment factor with analytic hierarchy process,assignment by expert system method,we have divided Wanzai county into high,middle and low probability area of geological disaster,which can provide the theoretical basis for the prevention and control of geological disaster in Wanzai.
