摘要
句容抽水蓄能电站碳酸盐岩分布广泛,岩溶发育强度属弱～中等.本文为分析影响该区域岩溶发育的诸多因素以及岩溶发育规律,综合运用地质调查法、统计分析法和经验法来对研究区岩溶发育规律与控制因素进行研究.根据地质条件和钻孔资料数据,将研究区岩溶划分为3个水文地质单元和1个非可溶岩水文地质单元,得到该区域岩性、断裂构造、节理、地下水和岩浆活动等在岩溶发育中发挥的重要作用,探讨该区域的岩溶发育规律如地层岩性和溶洞高程、埋深之间的关系等,研究结果能为水电站的施工和防渗设计提供科学依据.
Abstract
The Carbonate rock of Jurong Pumped-storage hydroelectricity is widely distributed,and the karst develop-ment intensity is weak to medium.In order to analyze many factors affecting the development of karst in this area and the law of karst development,this paper comprehensively uses geological survey,statistical analysis and empirical methods to study the law of karst development and control factors in the study area.Based on geological conditions and drilling data,the karst in the study area was divided into three hydrogeological units and one non soluble hydrogeologi-cal unit.The important roles played by lithology,fault structures,joints,groundwater,and magmatic activity in the development of karst in the area were obtained,and the karst development laws in the area,such as the relationship between stratigraphic lithology,karst cave elevation,and burial depth,were discussed,The research results can pro-vide scientific basis for the construction and design of hydropower stations.
