摘　　要：溪洛渡巨型水电站岩溶水渗漏研究 ,面临着范围大、地形地质条件复杂、基础资料缺乏 ,以及隐伏岩溶不易获取实证等多重困难。本文通过地质学、第四纪地质学、岩溶水文地质学等多学科联合 ,将零星不完整的各种资料进行了整体系统性的分析。运用定性分析与灰域模拟方法对库区岩溶发育、蓄水前后渗流特征进行综合性量化分析 ,对溪洛渡水电站库首岩溶渗漏可能性作出了较全面可信的评价。The analysis of leakage possibility of Xiluodu reservoir is faced with the difficulties of the prospecing in deep buried karst aquifers over large area with a precipitous topography. To counter these difficulties, multiple disciplines of geology, Quaternary geology, karst hydrogeology and hydrogeochemistry were integrated to synthesize odd data from different sources. Based on geological investigation, the charateristics of karst development, current flow pattern and the flow system after feservoir built\|up, were analyzed by a combination of quality analysis and gray domain simulation. Finally, the leakage possibility of the Xiluodu huge hydroelectric plant was successfully assessed.
