摘要
文章在对南宁市友爱立交桥桥墩结构进行耐久性检测的基础上,运用合理的钢筋锈蚀量数学计算模型,预测分析了该桥桥梁墩柱混凝土保护层锈胀开裂时间及其分布特征。结果表明,混凝土结构保护层锈胀开裂时间具有随机性,且总体服从正态分布。
On the basis of durability testing on the pier structure of Nanning Youai Overpass Bridge,the article applied propedy the mathematical computation model of steel corrosion amount,forecast and analyzed the corrosion cracking time of concrete protective layer of this bridge pier and their distribution features. The result showed that the corrosion cracking time of the concrete structure protective layer is random with an overall normal distribution.
