摘　　要：碳酸盐岩地区修建水库,库区渗漏是主要的工程地质问题,也是工程能否成立的关键性因素。在地质测绘、岩溶调查统计、钻探勘察及物探测试等基础上,从地形地貌、地层岩性、地质构造、水文地质、岩溶发育规律等方面深入分析库区渗漏的可能性。结果表明:水库库区存在近坝两岸库段及咪哩河-盘龙河库F区渗漏段,为防渗帷幕设计提供可靠的地质依据。Leakage in reservoir area is not only a major engineering geological problem,but also a key factor for the construction of reservoir in carbonate rock area.Based on geological mapping,karst investigation statistics,drilling investigation and geophysical exploration test,the possibility of leakage in reservoir area is analyzed in depth from the aspects of topography and landform,formation lithology,geological structure,hydrogeology and karst development law.The results show that there are seepage sections in reservoir area near both banks of the dam and in F area of Mili-Panlong Reservoir,which provide reliable geological basis for the design of impervious curtain.
