摘　　要：抗渗性是影响混凝土耐久性最主要的因素.为提高张掖国家湿地公园建筑物水下混凝土的耐久性,本项目通过对研究区域水体取样进行水质分析,并通过观测混凝土裂缝的长度、宽度和深度的发展,得出该区域建筑物水下混凝土的腐蚀类型主要为溶出型腐蚀,裂缝主要为表面裂缝、浅层裂缝、塑性沉降裂缝及塑性收缩裂缝.为此,文章提出相应的措施来提高湿地建筑物水下混凝土的耐久性,为该区域后续建筑物的设计和施工提供一定的参考.Impermeability is one of the main factors that influence the durability of concrete. To improve the durability of under water concrete structures in Zhangye National Wetland Park,through the sampling and analysis of the water quality then by observing the development of the length, width and depth of concrete crack,the research show that main corrosion types of concrete in National Wetland Park under water is dissolved corrosion, and cracks are mainly surface and shallow,plastic settlement and plastic shrinkage. So this paper puts forward corresponding methods to improve the durability of concrete structures under water,it also provides a reference for the design and construction for the regional follow-up buildings.
