Urban Karst Collapse Hazard Assessment Based on Analytic Hierarchy Process -Case Study on Wuhan Wuchang Map Sheet (1:50000)

摘要：

　　Based on the formation mechanism and influencing factors of karst collapse in Wuhan City,this paper selects 7 evaluation factors,and uses analytic hierarchy process (AHP) to construct the hazard assessment model of karst collapse in the study area,and divides 434 hazard assessment unit of karst collapse.According to each unit of karst collapse hazard comprehensive index,karst collapse hazard zoning,and deawing the wuchang map sheet of karst collapse hazard grade partition.It provides a reference basis for the prevention and control ofkarst collapse in Wuhan City.
