摘要
为进一步探明岩溶灾害塌陷发育特征及诱因,提高地质灾害治理成效,以枣庄某区域为调查研究区域,对岩溶塌陷分布规律、塌陷特征进行分析,并对该区域诱发塌陷的机制展开进一步探讨。研究确定了岩溶裂隙是产生塌陷灾害的基础条件,覆盖层的岩性结构是塌陷产生的主要因素,地下水过渡开采是塌陷产生的直接原因;确定了以渗透潜蚀、真空吸蚀和失托加荷效应为主的3种岩溶塌陷现象形成机制。针对该区域岩溶塌陷实际情况,提出通过对区内塌陷体及岩溶塌陷地表隐患点进行地面裂缝监测预防,通过减少城市水厂的开采量,关停区内中小型污染企业以减少开采岩溶水的方式进行灾害治理,为有效控制岩溶塌陷灾害提供一定的参考。
In order to further explore the occurrence,developmental characteristics and causes of karst disaster collapse and improve the effectiveness of geological disaster control,a region in Zaozhuang was taken as an investigation and research area to analyze the distribution law and characteristics of karst collapse,and to further explore the mechanism of inducing collapse in this region.It is determined that karst fissure is the basic condition of collapse disaster,lithologic structure of overburden is the main factor of collapse,and over-exploitation of groundwater is the direct cause of collapse.Three kinds of formation mechanisms of karst collapse phenomena are determined,which are mainly infiltration erosion,vacuum absorption erosion and loss of weight loading effect.According to the actual situation of karst collapse in this region,it is proposed that the disaster control should be carried out by monitoring and preventing ground cracks of the collapse body and the hidden hidden points of karst collapse in the area,reducing the exploitation of karst water by reducing the exploitation of urban water plant,and shutting down small and medium-sized polluting enterprises in the area,so as to provide certain references for effectively control-ling karst collapse disasters.
