基于序贯决策的桥梁多阶段维修加固策略优化方法
Optimization of multi-stage bridge maintenance strategies based on sequential decision-making
摘要
Abstract
To address the limitation of existing bridge maintenance optimization methods that fail to consider interactions between sequential decisions across the entire service life,this study proposes a multi-stage,two-level optimization framework grounded in sequential decision-making principles.The upper level model determines performance improvement goals for the maintenance sequence,while considering the influence of preceding decisions on subsequent maintenance policies.The lower-level model then identifies the optimal maintenance actions for each component at each stage,subject to the upper-level constraints.Case analysis shows that,while maintaining superior structural condition over the full life cycle,the proposed method reduces cumulative maintenance cost by 28.6%compared with the traditional strategies.Moreover,when the average deterioration rate of the performance condition index is below 1.425 per year,total life-cycle maintenance and rehabilitation cost can be further reduced by reducing the number of decision-making stages.关键词
