摘要

美国全国的桥梁结构正在老化，需要维修，或者在某些情况下需要完全更换。与完全更换损坏或损坏的桥
梁部件（如大梁）的更高成本相比，修复决定在桥梁所有者中很常见，因为其经济可行性。使用适当的维修方法，
作为一种长期或短期的解决方案，可以带来其他方式无法实现的好处，例如节省大量时间和成本。此外，适当的维
修方法可以帮助避免不利的环境影响、服务中断、附近基础设施负担过重以及当地反对建设。本文的主要目的是综
合研究中所提出的钢筋混凝土桥梁的修复方法和材料，即最先进的以及最先进的已建立方法，并且讲述了一般维修
过程中的不同步骤。这旨在使研究人员、工程师和决策者能够更方便地比较可用的修复方法，以根据经济和环境要
求以及结构和施工条件为特定项目找到最佳修复方法。
