RESEARCH ON UPPER RESERVOIR SEEPAGE ISSUES OF PUMPED STORAGE POWER STATION

Based on research characteristics of upper reservoir seepage, the paper constructs the engineering geological analysis system of upper reservoir seepage. The application of the system was beneficial to analyze and evaluate issues from upper reservoir seepage of special Pumped Storage Power station. The result shows that seepage lengths in the upper reservoir bank is 90 percent of total length of the ring reservoir, and seepage areas mainly concentrate in the dam area, right bank or tail of reservoir. So the article suggests the upper reservoir bank should adopt seepage control measures for the whole area.
