Abstract: Increasing with the service time of large numbers of bridge, assessing and reinforcing of bridge became increasingly to be important part of maintaining of old bridge. As a space analysis technics of bridge, it has predominant that application of space integrated element method to assessing and reinforcing of old bridge. As the examples, application of space integrated element method to several really engineering was introduced, thereby it provided technology reference for assessing and reinforc...

Key words: assessing of old bridge, reinforcing of old bridge, space integrated element method

摘要： 随着大量在役桥梁运营年限的增加，旧桥运营技术状态的评估及加固日益成为已有桥梁养护和维修工作的 重要组成部分。空间组合有限元法作为近年来桥梁空间行为分析中日趋成熟的分析技术，在旧桥评估及加固中具 有得天独厚的优势。结合实际工程，介绍了空间组合有限元法在旧桥评估及加固中的具体应用实例，为旧桥运营 技术状态的优良评估及加固提供了技术参考。
