摘　　要：水利工程在自然环境中遭到物理、化学侵蚀以及运行多年后,会出现混凝土构件的碳化。碳化会降低构件的稳定、形成收缩裂缝、引发钢筋绣蚀进而影响结构安全。混凝土碳化深度不同,碳化部位不同,对其处理方案也要不同。结合人民胜利堰节制闸除险加固工程,叙述防碳化处理方案选择的方法。The carbonization of concrete components will occur after years of physical, chemical erosion and operation of water conservancy projects in the natural environment. Carbonization will reduce the stability of the components, form shrinkage cracks, cause corrosion of steel bars and then affect the safety of the structure. The carbonization depth of concrete is different, and the carbonization parts are different, and the treatment plan of concrete should be different. Combined with the reinforcement project of the people＇s victory weir sluice, the selection method of the anti-carbonization treatment scheme is described.
