摘要
为了对桥梁有的放矢地进行管理和维护,在城市轨道交通高架桥梁的寿命周期中,保证最优化的维护成本和最可靠的结构性能,需要对结构性能作出准确的判断和预测.通过马尔科夫过程对桥梁结构性能进行分析和预测,得到了与时变可靠度理论相一致的结果.从而不仅可以评定结构的未来等级,还有助于进一步建立结构等级与维护成本的关系方程.
During the lifespan cycle of the urban transportation bridge, the structure performance should be analyzed and predicted clearly to keep the appropriate maintenance work, gurantee the optimized maintenance cost and the most reliable structure performance. The similar result from time-variant-reliability theory can also be acquired by Markov process on the bridge structure. Furthermore, the Markov process can not only predict the structure future performance, but set up the relation equation of the structure class and maintenance cost.
