一、调查目的与方法 近年来,我国华南、华东地区部分工程许多构件混凝土顺筋开裂、剥落,钢筋锈蚀问题较为严重。为了摸清情况,总结经验教训,提高工程耐久性能,也为今后港工、水工钢筋混凝土技术规范的修订累积资料,镇海县水利局和华东水利学院自1984年5月至7月,对县内的部分水闸工程的锈蚀破坏情况联合进行了调查。
First, the purpose and methods of investigation In recent years, many of China’s southern China, East China region, a lot of concrete components along the tendons cracking, spalling, steel corrosion problems more serious. In order to find out the situation, to sum up experiences and lessons learned to improve the durability of the project, but also for the future Hong Kong, hydraulic reinforced concrete technical specifications of the cumulative data, Zhenhai County Water Conservancy Bureau and East China Institute of Hydraulic from May 1984 to July, Within the part of the sluice project corrosion damage jointly conducted a survey.
