Abstract: Based on the analysis of dam seepage monitoring data, seepage safety of Siminghu reservoir was analyzed comprehensively. The result showed that: geomembrane was good at preventing seepage; seepage stability of dam and foundation could meet the requirements; there was a little leakage; seepage pressure at dam foundation increased slightly; there was almost no seepage around the dam; dam safety was generally good. It was suggested that dam check should be strengthened and seepage observation should be carried out as high water level. As well, monitoring data should be reorganized and analyzed in time so that engineering safety can be achieved.

Key words: Siminghu reservoir, dam, seepage, safety analysis
