摘　　要：岩溶发育规律是影响库区岩溶渗漏评价的关键因素,通过多维度勘察方法,对万家寨库区岩溶发育情况进行了系统研究,基本查明了岩溶发育的基本规律、渗漏形式,通过示踪试验和数值模拟对渗透量进行了估算,创新了岩溶渗漏评价方法。水库蓄水后监测渗漏量比前期勘察结论预估略大,渗漏量仍在前期勘察的预测范围附近,库区岩溶渗漏量对大坝和电站的运行基本没有影响。The law of karst development is the key factor affecting the evaluation of karst leakage in the reservoir area.Karst development situation in Wanjiazhai Reservoir area is systematically studied with multi-dimensional survey method,in which the basic law and leakage form of karst development are basically found out.The seepage volume is estimated by tracer test and numerical simulation,and the karst leakage evaluation method is innovated.After impoundment of the reservoir,it is found that the detected leakage is slightly larger than that predicted by the previous survey,but the leakage is still around the prediction range of the preliminary investigation,therefore,the karst leakage in the reservoir area has little effect on the operation of the dam and power station.
