摘　　要：本文以安徽省淮南市大通区梨园为例,简要描述其区域地质概况,根据历史发生岩溶塌陷现状特征进行统计并简要分析,结合高密度电法及地质钻探成果对该区岩溶发育特征进行分析,并根据塌陷现状对岩溶塌陷的稳定性进行评价。岩溶发育程度主要受灰岩裂隙岩性特征及其推覆体构造控制。该地区偶有小型塌陷发生,稳定性属基本稳定。Focusing on Liyuan,Datong District,Huainan City,Anhui Province,this paper briefly introduces the regional geology,makes statistics of current features of karst collapses that occurred in the history,analyzes the features of karst development in the district using high-density electrical method and geological drilling results,and evaluates the stability of karst collapse in current situation.The degree of karst development is mainly controlled by the lithologic characteristics of limestone fractures and nappe structure.The district is basically stable with occasional small collapses.
