前言六甲水电站是龙江上最先开发的低水头径流电站,1967年建成,蓄水发电十多年来,运行正常,库坝未发现有明显的漏水问题。继六甲水电站后,1972年在其上游又建成了规模与其相当的拔贡水电站,蓄水发电后不久,就发现坝基有严重渗漏,至今尚未得到有效的治理。本文对这两个水电站的岩溶渗漏条件作一初步的分析,并谈几点在岩溶地区修建水电工程的体会。

Preface Liujia hydropower station is the first developed on the Longjiang low head runoff power station built in 1967, water storage power generation over the past 10 years, the normal operation, the reservoir dam found no obvious leakage problems. Following the Liujia Hydropower Station, a similar scale of the Begonjig Hydropower Station was built in 1972 in its upper reaches. Shortly after water storage and power generation, there was a serious leakage of the dam foundation and so far no effective treatment has been achieved. This paper makes a preliminary analysis on the karst seepage conditions of these two hydropower stations and also discusses some experiences on how to construct hydropower projects in karst areas.
