龙滩水电站自1958年开始进行规划研究以来,相继进行了大量的地质勘探工作,至今已完成岩心钻孔16,000多米,平硐5,000余米,竖井近200米,槽坑约40,000米。,并进行了各种比尺的地质测绘、物理勘探,室内外岩土力学试验,水文调查和分析计算,以及相应阶段的设计工作,获得了大量基本资料。1981年4月正式选定了龙滩坝址,目前正在进行可行性研究的工作。
Since 1958, Longtan Hydropower Station has carried out a large number of geological exploration work successively. Up to now, more than 16,000 meters of cores have been drilled, more than 5,000 meters of adit holes, nearly 200 meters of shafts and about 40,000 meters of trenches have been completed. , And conducted a variety of scale geological mapping, physical exploration, indoor and outdoor rock and soil mechanics tests, hydrological survey and analysis and calculation, and the corresponding stage of the design work, access to a large number of basic information. In April 1981, the site of Longtan was officially selected and work on feasibility study is currently underway.
