A Tracing Test of Karst Leakage on the Right Bank of Wanjiazhai Reservoir
万家寨水库右岸岩溶渗漏试验研究

The karst leakage on the right bank of the Wanjiazhai water conservancy facilities is a hidden trouble in the safe operation of the reservoir, and hence much attention was paid to it during the exploration and designing of the reservoir. In the course of water storage for the reservoir, the authors conducted researches on the key leakage segments with the tracing test and some other methods. The leakage ways and intensity were detected and the feasible method for the investigation of the karst leakage of the reservoirs in the northern part of China was thus suggested.
