铁路钢筋混凝土拱桥碳化寿命分析

The Carbonate Life Span Analysis of the Railway Reinforced Concrete Arch Bridge

根据某在役铁路钢筋混凝土拱桥的测试数据,结合工程环境和使用条件,利用可靠度理论以及混凝土碳化深度预测模型,对该桥进行了碳化寿命评估检测和分析.结果表明,该桥的剩余碳化寿命可满足使用要求.

According to the testing result of a railway reinforced concrete arch bridge, in conjunction with the employed environment and condition of the bridge, apply the reliability theory and the model of carbonate life span of the bridge, calculate the carbonated durability year of the bridge, the result of residual carbonated durability can satisfy the bridge requirement.
