摘　　要：本文以桐柏县朱庄镇朱庄村岩溶地面塌陷为例,收集了研究区地质环境资料、水文地质资料及工程地质资料,选取基岩岩性、岩溶发育程度、覆盖层厚度、透水能力、水位波动幅度、地下水位埋深六个主控因素,将层次分析法(Analytic Hierarchy Process,简称AHP)确定的权重与GIS处理的各主控因子专题图进行叠加,进而对桐柏县朱庄岩溶地面塌陷进行危险性分区评价。根据与已发生的塌陷对比,验证了AHP-GIS耦合评价在朱庄岩溶地面塌陷危险性评价应用中结果的准确性,已发生岩溶塌陷点几乎都位于高危险区。评价结果可为朱庄岩溶地面塌陷的防治提供参考依据,评价方法对其他岩溶地面塌陷危险性评价具有借鉴意义。This article takes the karst ground collapse in Zhuzhuang Village,Zhuzhuang Town,Tongbai County as an example,and collects geological environment data,hydro-geological data,and engineering geological data from the research area.Six main control factors are selected,including bedrock lithology,karst development degree,cover layer thickness,permeability,water level fluctuation amplitude,and groundwater level burial depth,By overlaying the weights determined by Analytic Hierarchy Process(AHP)with the thematic maps of various main control factors processed by GIS,the risk zoning evaluation of karst ground collapse in Zhuzhuang,Tongbai County is conducted.Based on the comparison with the collapse that has occurred,the accuracy of the AHP-GIS coupling evaluation results in the risk assessment of karst ground collapse in Zhuzhuang has been verified.Almost all the karst collapse points that have occurred are located in high-risk areas.The evaluation results can provide a reference basis for the prevention and control of karst ground collapse in Zhuzhuang,and the evaluation method has reference significance for the risk assessment of other karst ground collapses.
