摘要
水工混凝土建筑物的安全运行是有关国计民生的重大问题，因此建筑物因老化而产生的病害及其修补技术日益受到各级有关部门的重视．水工混凝土建筑物由于耐久性不良而产生的病害种类较多，但从外观破坏上总的可分为三大类，即裂缝、渗漏及剥蚀，冲磨和空蚀剥蚀、钢筋锈蚀产生的混凝土保护层剥蚀、水质化学侵蚀以碱活性骨料反应而产生的混凝土剥蚀．本文在总结我国水工混凝土建筑物病害处理技术的经验教训基础上，详细地介绍了五类剥蚀破坏的修补技术，从修补材料的选择适用范围、技术关键，直至施工工艺均作了说明．
The safty operation of mass concrete construction is of vital importance to the national econorny and peoples's livelibood. The defect due to the ageing of constrution and the repairing techniques have drawn more and more concern. There are three kinds of defects according to the damaged appearance due to the poor durability of mass concrete. These are cracking,leakage and deterioration. According to the damaged mechanism. the deterioration can be classfied as:freezethaw,wear and abrasion,steel corrosion,chemical corrosion of surrounding water and alikali -aggregate reaction. This paper presents the technique for repairing different defects and pro-vides the helpful aid for the department of design,managetnent and construction to repair and re-habilitate the mass concrete by suming up the experience and lessons of repairing mass concretedefects.
