摘　　要：蔺河口碾压混凝土拱坝以二级配富胶凝材料碾压混凝土及变态混凝土自身作为防渗体为主,大坝死水位以下涂刷LJP型合成高分子防渗涂料,作为辅助防渗措施。通过涂料材质性能试验,证明该涂料可以满足施工需要,并可以简化防渗结构,方便施工,大坝自2003年10月27日蓄水运行以来,防渗效果良好。This paper introduces mainly the properties of the impermeable dope and its application in the construction of RCC arch dam for Linhekou Hydropower Station. As a supplementary impermeable measure, it strengthened the impermeability of the two-grade rich colloid material and made it possible in the use of metamorphic concrete in upstream section of the RCC dam. So it simplified the impermeable structure of the RCC dam, and made the construction convenient. The effect of the seepage control is satisfactory since the filling of the reservoir on October 27,2003.
