摘　　要：一般的水工建筑物混凝土缺陷指裂缝、混凝土内部欠密实和局部架空、低强、渗漏以及表面不平整缺陷。出现混凝土缺陷将产生渗漏,渗漏会引起析钙和钢筋锈蚀。混凝土缺陷处理应采取“预防为主”的方针,出现混凝土缺陷需要采取切实、可行的处理措施加以修补,以满足设计要求及结构的正常性能。General concrete defects of hydraulic structures refer to cracks,under-compactness in concrete and partial overhead,low strength,leakage and surface irregularity defects.Leakage occurs when concrete defects occur,which can lead to calcium precipitation and corrosion of steel bars.The treatment of concrete defects should take precautions as the main principle,and the concrete defects need to be repaired by practical measures to meet the design requirements and normal performance of the structure.
