摘要
介绍了由于存在裂缝、混凝土碳化、钢筋锈蚀、渗漏和溶蚀、冻融冻胀、剥蚀和气蚀、水质侵蚀和混凝土碱集料反应等病害,我国水利工程的耐久性普遍不足,水工建筑物的使用年限不长的情况,提出为了改善水利工程的耐久性,应从建筑物材料、设计、施工、运行管理等方面采取适当的预防对策,以延长工程的使用寿命.这些对策的具体内容,可供水工建筑物耐久性设计和制订水利工程耐久性规范时参考.
Owing to various factors such as cracks, carbonization of concrete, rust of reinforcement, seepage and corrosion, freezing and thawing, swelling, denudation and cavitation, water erosion, alkaline aggregate reaction, etc, the hydraulic structures of the country are poor in terms of durability and the service life is not very long. For improving the durability of hydraulic structures and prolonging their service period some preventive counter measures have to be adopted for their materials, design, construction and exploitation. This will provide a strong basis for improving the durability of hydraulic structures, as well as for satisfying the need for preparing related specifications.
