摘　　要：近年来枣庄市岩溶塌陷频繁发生。通过野外地质调查、现场采样和室内试验相结合的综合手段,对该区的岩溶塌陷覆盖层进行系统地取样并进行深入细致的实验及分析,论述了覆盖层特征对该区岩溶塌陷的影响;运用宏观调查、细观测量和微观分析相结合的研究方法详细论述了地质构造对岩溶塌陷的影响;结合历年水文动态资料、地下水开采量等论述了地下水活动对岩溶塌陷影响。综合认为,地层岩性、覆盖层性质、构造因素是枣庄岩溶塌陷频繁发生的内因,而超量开采地下水则是外部诱发因素。In recent years, karst collapses have frequently occurred in Zaozhuang City. With geological investigation, in-situ sampling and laboratory experiments, we have systematically collected, tested and analyzed samples of the cover materials that overlay zones of karst collapses. We discuss the influence of the characteristic features of these overlaying covers in Zaozhuang. By applying the methods of macroscopic survey, detailed measurements and microanalysis, we have investigated in detail the influence of geological structures on karst collapse. Based on hydrological conditions, groundwater exploitation, etc., we discuss the influence of groundwater activity on the karst collapse in Zaozhuang. We conclude that the rock types, the characteristics of overlaying covers and geological structures are the internal factors causing the karst collapse, while excessive exploitation of groundwater is an important external factor involved in karst collapse.
