岩溶塌陷危险性的层次分析法评价

Risk Assessment of Karst Collapse Based on Analytic Hierarchy Process

在收集、整理岩溶塌陷地质影响因素相关数据的基础上,采用层次分析法(AHP)确定临沂岩溶塌陷影响因素在岩溶成因中的比重,绘制综合主要影响因子的危险等级量化指数分区评价图对该区域岩溶塌陷危险性进行评估.与以往研究成果对比分析发现,在可利用的地质数据范围内,所用的分析方法在技术上更准确可靠.

On the basis of collecting and sorting out the relevant data of karst collapse geological factors,the proportion of karst collapse influencing factors in Linyi area karst genesis was determined by analytic hierarchy process for the first time,and the risk assessment map of karst collapse in this area was drawn by using the quantitative index zoning evaluation map of the above influencing factors.Compared with the previous research results,it is found that within the available geological data range,the analysis method is technically accurate and reliable,and can be used for comprehensive evaluation of karst collapse in the whole region.
