摘要
基于1:5万水文地质和水资源调查,利用探采结合井等技术手段研究赣南青塘地区岩溶发育特征与规律。结果表明,青塘地区共有3个岩溶盆地,其中,王干盆地揭露溶洞35个,溶洞高一般为1~2 m,最高的11.28 m,最低的0.3 m,钻孔线岩溶率达15%;青塘盆地揭露溶洞24个,溶洞一般为1~5 m,最高的26.91 m,钻孔线岩溶率13%;梅窖盆地揭露溶洞6个,溶洞高一般为0.59~1.80 m,最高的8 m,钻孔线岩溶率3.6%。综合分析认为,区内岩溶主要受控于断裂构造、层面及侵蚀基准面的控制。研究青塘地区岩溶发育特征与规律,对工程选址建设和岩溶塌陷等地质灾害防治提供科学依据。
Based on 1:50000 hydrogeological and water resources surveys,the characteristics and laws of karst development in Qingtang area were studied by means of exploration and production Wells.The results show that there are three karst basins in Qingtang area,among which,there are 35 karst caves in Wanggan basin.The height of karst caves is generally 1~2 m,the highest is 11.28 m,the lowest is 0.3 m,and the karst rate of borehole is 15%;There are 24 exposed karst caves in Qingtang basin,the karst caves are generally 1~5 m,the highest is 26.91 m,and the karst rate of drilling holes is 13%;There are six karst caves in Meijiao basin.The height of karst caves is generally 0.59~1.80 m,the highest is 8 m,and the karst rate of boreholes is 3.6%.The comprehensive analysis shows that the karst is mainly controlled by fault structure,plane and erosion base plane.The study of karst development characteristics and laws in Qingtang area provides scientific basis for the site selection of important projects and the prevention of geological disasters.
