The performance of reinforced concrete bridge deck pavement will be gradually reduced with the increase of operation time, so the reasonable maintenance measures should be taken to ensure the performance and safety of the bridge structures. The objectives and their hierarchical structures from both state position and enterprise position of the decision makers in bridge engineering decision-making problems were discussed. By the existing deterioration model, this paper studies the bridge operation safety maintenance strategy, establishes the mathematical model of the influence of different degrees of maintenance measures on the structural performance, combines with the cost-benefit theory, establishes the maintenance risk decision criteria for the decision makers with different objectives, and makes the decision on the selection of the bridge deck pavement scheme based on the enterprise position through an example.

基于决策者目标的桥面路面养护决策方法

钢筋混凝土桥面铺装的性能会随着运营时间的增加而逐渐降低，因此应采取合理的养护措施，以保证桥梁结构的性能和安全。从决策者在桥梁工程决策问题中的国家立场和企业立场两个方面讨论了决策者的目标及其层次结构。以现有的劣化模型为基础，研究桥梁运营安全养护策略，建立不同养护措施对结构性能影响的数学模型，结合成本收益理论，建立桥梁运行安全维修风险决策准则。具有不同目标的决策者，
