关于T型梁桥维修加固设计的计算——滦河大杖子桥加固设计实例

目前已经修建运营的各地城镇和各级公路上的桥梁，由于种种历史原因，在施工过程中留下许多缺陷，给桥梁的安全带来一定程度的影响。结合滦河大杖子桥的施工实例，对旧桥维修加固设计进行计算比较，提出有效可行的解决方案，不但解决了公路桥梁的现状问题，而且经济合理，值得推广应用。

Calculation of T-type Beam Bridge Maintenance Reinforcement Design--A Case of Luanhe Dazhangzi Bridge Design

Because of several historical reasons, many built bridges in many towns and highways have many defects during construction, which have negative influence on bridge safety. According to Luanhe Dazhangzi bridge construction experiences, the old bridge maintenance reinforcement design is computed and compared, and finally an efficient solution scheme is put forward, which not only solves the bridge problems, but also is economical and reasonable, worth of spreading.
