摘要
文章聚焦城市桥梁耐久性评估与维护策略,重点研究了钢筋混凝土简支T形梁桥的耐久性问题。采用物元扩展理论和熵权法对T型甲桥进行了全面的耐久性评估,分析了材料老化、环境因素和载荷变化等多重因素对桥梁耐久性的影响。基于评估结果,提出了一系列维护策略,旨在提高桥梁的整体耐久性并延长使用寿命。文章的研究为城市桥梁的长期维护和安全运营提供了有价值的见解和建议。
This paper focuses on the durability assessment and maintenance strategy of urban bridges,and focuses on the durability problem of reinforced concrete T-beam bridge.This paper evaluates the durability of T-type A bridge,and analyzes the influence of multiple factors including material aging,environmental factors and load change.Based on the evaluation results,a series of maintenance strategies are proposed,aiming to improve the overall durability of the bridge and extend the service life.The study of the article provides valuable insights and suggestions for the long-term maintenance and safe operation of urban bridges.
