摘　　要：随着我国公路建设的快速发展,桥梁数量越来越多,再加上新的公路工程技术标准发布实施,桥梁汽车荷载提高,使得原标准建设的桥梁承载力不能够满足要求。以某公路预应力箱形梁桥为实例,运用midas Civil对桥梁进行分析计算后,采用粘贴钢板对桥梁进行加固处理,经复核,加固后能够满足承载力要求。通过应用实例,总结桥梁加固技术的一些经验,为相关桥梁专业技术人员提供一些经验。With the rapid development of highway construction in China,more and more bridges are built.In addition,with the release and implementation of new technical standard of Highway Engineering,the vehicle load of the bridge is increased,so that the bearing capacity of the original standard can not meet the requirements.This paper takes a highway prestressed box girder bridge as an example,uses Midas civil to analyze and calculate the bridge,and pastes steel plates to reinforce the bridge.After rechecking,the strengthened bridge can meet the requirements of bearing capacity.This paper sums up some experience of bridge reinforcement technology through application examples,and provides some experience for relevant bridge professional technicians.
