摘　　要：在渗流监测资料分析的基础上,分析了四明湖水库大坝的渗流安全状况。分析结果表明:土工膜对坝体起到了很好的防渗功效,坝体和坝基渗透稳定性满足要求,坝基渗流压力略有增大趋势,渗流量较小,左、右坝肩基本无绕坝渗流问题,大坝安全性态总体较好。建议加强对大坝巡视检查并在高水位下进行渗流观测,及时对监测资料进行整编分析,保障工程安全。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.
