山东平邑地质灾害重点风险区岩溶塌陷易发性评价及对策研究分析
Study and Analysis on the Susceptibility Evaluation and Countermeasures of Karst Collapse in Key Risk Area of Geological Disasters in Pingyi County in Shandong Province
摘要
Abstract
Abstracr:Karst collapse has occurred many times along traffic lines,such as Yanshi Railway and G327 Na-tional Road in key risk areas of geological disasters in Pingyi county.Although no personnel casualties have been caused,the area is densely populated and karst collapse occurs easily.It will bring security risks to social stability.Based on analysis of existing data,the influencing factors and genetic mechanism of karst collapses in main risk areas in Pingyi county have been analyzed from the aspects of overburden,karst development degree,geological structures,groundwater level change and mechanical vibration.Se-lecting seven influencing factors of karst collapse as evaluation indexes,by using AHP method,the weight of each evaluation index has been calculated,and a targeted evaluation index system has been constructed.Combining with GIS spatial analysis method,the susceptibility of karst collapse has been evaluated,and suggestions for prevention countermeasures have been put forward.关键词
