| 摘 要： | 在介绍了引起钢筋锈蚀的因素及过程后,分析了钢筋锈蚀造成结构性能退化的机理,并分析钢筋的锈蚀对桥梁结构的影响。通过对钢筋锈蚀引起结构抗力衰减过程分析,建立了结构抗力的等效模型,分析结构评价时刻的可靠度,并与初始状态进行比较,建立了基于桥梁检测结果的可靠性分析方法。以实现对桥梁当前和将来状态的可靠性评估及预测。

| Abstract: | After analyzing the process and the factor causing the corrosion of steel bar on bridge structure,and the mechanism that the reinforcing bar's rust results in deterioration of construction function.Through analyzing the process of the construction resistance's reducing,the replacement model of the construction resistance is established.By evaluating reliability of the bridge currently,and comparing with the initiatory moment,the method to analysis the reliability of the bridge based on inspection is built,which can evaluate and forecast the current or future reliability. |
