摘要： 某水利枢纽尾水闸墩水位变化区混凝土出现不同程度的冻融破坏。笔者介绍了采用薄层水下不分散混凝土对尾水闸墩冻融破坏部位进行修复处理的相关施工工艺，提出了施工中的关键技术及难点，为同类工程施工提供了宝贵经验。
关键词: 冻融破坏, 水下不分散混凝土, 尾水闸墩
Abstract: Different degrees of freeze-thaw damage appeared on the concrete in water-level-change area of the tail water sluice pier of a conservancy project. This paper introduces an engineering technology which uses a thin layer of underwater non-dispersive concrete to repair freeze-thaw damage in the tail water sluice pier. As well, the key technology and difficulty in construction are proposed, worthy reference for similar projects.
Key words: freeze-thaw damage, underwater non-dispersive concrete, tail sluice pier
