工字钢-混凝土组合梁在危桥改造中的应用

Application of I-Steel-Concrete Composite Beams in the Reconstruction of Dangerous Dridges

公路运输是经济发展的关键,而桥梁又是公路运输的重要组成部分,因此,保证桥梁的正常运营是经济发展的必要条件。论文以临园大桥为背景,从方案对比到桥位涂装,对该桥的整体设计及施工过程进行了详细描述。本项目中采用工字钢-混凝土组合梁对桥梁原上部结构进行更换,能够大大缩短施工周期,降低施工难度,提高结构承载力,修复原有病害,达到顺利改造的目的。

Highway transportation is the key to economic development,and the bridge is an important part of highway transportation.Therefore,to ensure the normal operation of the bridge is a necessary condition for economic development.Taking Linyuan bridge as the background,this paper describes the overall design and construction process in detail from scheme comparison to bridge coating.In this project,I-steel-concrete composite beam is used to replace the original superstructure of the bridge,which can greatly shorten the construction period,reduce the construction difficulty,improve the structural bearing capacity,repair the original diseases,and achieve the purpose of smooth transformation.
