摘　　要：依托兖州滋阳山地区岩溶塌陷地质勘查成果,选择3个一级指标,8个二级指标将研究区岩溶塌陷易发性级别划分为易发性极低、低、中等、高、极高五个级别,一级指标为基岩条件、覆盖层条件和地下水动力条件,二级指标为岩石地层岩性、岩溶发育程度、覆盖层厚度、覆盖层结构、覆盖层底部地层岩性、覆盖层底部土层状态、岩溶水位与基岩面的垂距、年水位变幅8个影响因子,通过层次分析法构建的易发性判断矩阵,获得了11个指标的权重赋值,进行了易发性评价。易发性高区分布于滋阳山山体西侧以及东北侧一带,易发性中区分布在滋阳山岩体出露周围一带。Based on the geological exploration results of karst collapse in the Ziyang Mountain area of Yanzhou,three primary indicators and eight secondary indicators were selected to divide the susceptibility level of karst collapse in the study area into five levels:extremely low,low,medium,high,and extremely high.The first level indicators include bedrock conditions,cover layer conditions,and groundwater dynamic conditions,while the second level indicators include rock formation lithology,karst development degree,cover layer thickness,cover layer structure,bottom layer lithology,bottom soil layer status,vertical distance between karst water level and bedrock surface,and annual water level variation.The susceptibility assessment matrix was constructed using the Analytic Hierarchy Process,and the weight assignments of 11 indicators were obtained for susceptibility evaluation.The high-risk areas are distributed on the west and northeast sides of the Ziyang Mountain,while the high-risk areas are distributed around the exposed Ziyang Mountain rock mass.
