The Pubugou hydropower dam is the highest core wall rockfill dam in China at present which makes the wide grading gravelly soil as the anti-seepage material of core wall dam. Its foundation lies on a deep riverbed overburden layer with the maximum depth of 78 m. Two fully enclosed concrete diaphragm walls, 1.2 m thick each, are used for seepage prevention. The paper introduces the safety monitoring of the anti-seepage wall. The result shows that the construction quality of the anti-seepage wall is excellent. As well, it is of good effect which meets the requirements in design. The success of anti-seepage project at Pubugou hydropower station witnesses the high level in construction which is worthy reference.
