Abstract

Abstract: Taking Tiancheng primary experiment school landslide as an example authors make some sensitive analysis to risk factors of Landslide disaster and found assessment method of risk zoning in this paper. The method include fours step, the fist select eight risk factors through grey assemble theory and connected degree, and the second is endowing value to every factor in the Analytical Hierarchy Process (AHP) and the Dephel method. The third is calculating risk index through GIS system to Tiancheng p...

Key words: experiment school landslide, risk factors, risk index, zoning, assessment

摘要： 通过对重庆库区松散土体滑坡灾害危险性影响因素的分析,构建了滑坡危险性分区评价方法,即运用灰色聚类理论和关联度法遴选8个危险性因子,并用层次分析方法量化其权重系数以及用专家系统评分法给每一危险因子分级赋值.以重庆市万州区天城实验小学滑坡为例,用等面积网格法,通过GIS系统空间多因子叠加获取其危险性指数并绘制其危险性等值线图,据危险性指数进行其危险性分区并对其进行评价
