| 摘 要： | 结合某灌注桩旧桥实际工程，在考虑经济因素的基础上，对该桥进行加固处理，拆除原上部结构，用增大截面法加固盖梁。通过对该旧桥进行盖梁承载力验算分析，以确保加固后的承载力满足当前荷载要求。研究结果表明：该桥加固前承载力已经不满足当前荷载要求，通过对该桥加固处理，加固后承载力验算，该桥完全满足现阶段荷载要求。而且加固后的盖梁也完全符合设计要求，从而达到了保留下部结构，节约资金的目的。

| Abstract: | The article combines practice project of certain cast-in-place pile bridge,reinforcing the bridge on the base of economy,removal of superstructure,and reinforcing the coping by enlarging cross-section.Through the research for load-carrying capacity of the old bridge,being sure the load-carrying capacity of reinforcing bridge meets the load requirement.The research indicates that load-carrying capacity of bridge meet the load requirement.Through checking calculation about reinforcing the bridge,the load-carrying capacity of reinforcing bridge meets the load requirement.The coping meets the design fully,and achieves the target of saving money. |
