摘　　要：某小型水库坝体为浆砌石拱坝,经多年运行,坝体背水面出现了较大面积潮湿现象,存在一定的安全隐患。为及时消除安全隐患,确保坝体的整体稳定性,设计采用高性能改性聚合物修补砂浆和单组分聚脲防水涂料对坝体迎水面进行整体修复加固与防渗处理。笔者详细介绍了高性能改性聚合物修补砂浆和单组分聚脲防水涂料的性能特点,以及采用这两种材料进行防渗加固处理的施工工艺和质量控制要点。结果表明,两种材料组合使用在水库防渗加固处理中取得了良好的效果,既满足了工程应用要求,又简化了施工过程并降低了工程投资。The dam body of a small reservoir is a masonry arch dam.After years of operation there is a large area of moisture on the back surface of the dam body which has certain safety hazards.In order to eliminate the potential safety hazards in time and ensure the overall stability of the dam body high performance modified polymer repair mortar and one-component polyurea waterproofing coating were designed to carry out the overall repair reinforcement and anti-seepage treatment of the dam surface.The authors introduce in detail the performance characteristics of high performance modified polymer repair mortar and one-component polyurea waterproofing coating as well as the construction technology and quality control points of anti-seepage reinforcement using these two materials.The results show that the combination of the two materials has achieved good results in the reservoir anti-seepage reinforcement which not only meets the requirements of engineering application but also simplifies the construction process and reduces the project investment.
