摘　　要：为了消除锦屏水电站上游坝面裂缝隐患,提高大坝工程安全运行寿命,结合锦屏水电站的特点和具体要求,设计和施工单位采用了聚脲作为防渗材料。介绍了锦屏水电站上游坝面裂缝喷涂聚脲防渗处理的施工方法。1年多的工程运行实践表明,聚脲防渗效果较好,达到了预期效果。In order to eliminate the risk of cracks in the upstream face of arch dam in Jinping Hydropower Station and improve the operational life of dam, the polyurea is selected as the seepage control material by design and construction companies after considering the characteristics and requirements of Jinping Hydropower Station. The construction method of polyurea for the upstream cracks of Jinping dam is introduced. More than one-year operation of project shows that the seepage control by polyurea is better and achieves desired effect.
