摘　　要：通过探讨硅烷疏水处理对水工混凝土耐久性性能的影响,解决混凝土水闸在潮湿、含氯环境中的耐久性问题。选择江苏淮安市清江水闸作为研究对象,采用不同水胶比的混凝土试件,进行硅烷疏水处理,并通过氧气渗透性指数(OPI)、水吸附性指数(WSI)和氯离子导电性指数(CCI)等耐久性指标进行评估。结果表明,硅烷疏水处理有效减少了混凝土的毛细吸水性、氯离子扩散性和氧气渗透性,显著提高了混凝土的耐久性。研究结果为水利工程中混凝土结构的耐久性保护提供了理论依据和实践指导。By exploring the influence of silane hydrophobic treatment on the durability performance of hydraulic concrete,the durability problem of concrete sluices in humid and chlorine-containing environments is solved.The Qingjiang Sluice in Huai’an City,Jiangsu Province is selected as the research object.Concrete specimens with different water-binder ratios are subjected to silane hydrophobic treatment and evaluated through durability indexes such as the oxygen permeability index(OPI),water sorption index(WSI),and chloride ion conductivity index(CCI).The research results provide theoretical basis and practical guidance for the durability protection of concrete structures in hydraulic engineering.
