摘要
运用可靠度分析方法,以桥梁结构服役状态下材料性能的劣化为出发点,对结构的承载能力耐久性进行了分析。MonteCarlo模拟方法的运用,将桥梁的实际检查结果与结构分析紧密地结合起来。通过高次(五十万次)模拟,数据分布表现出了很好的规律性和重复性。在建立材料性能劣化模型的情况下,该种方法可以作为桥梁生命周期成本管理系统的基础,为桥梁养护、管理优化提供依据。
By means of reliability analysis, the paper analyses the carrying capacity's durability of in-service bridges based on the structural material's deterioration. Using the Monte Carlo simulation method, the structural analysis is tightly combined with the actual bridge inspection results. The data distribution expresses excellent regularity and repeatability by high order simulation. On the condition of establishing material's deterioration model, this method can be used as the basis of bridge life-long management system and provides foundation for bridge's maintenance.
