摘　　要：随着城市建设的发展,部分已建桥梁因其使用功能无法满足现代城市需求,但考虑到节约成本的需求,实际施工中仍需保留桥梁主体结构。为减少施工过程中建筑垃圾的产生和对交通的影响,桥梁顶升工法已成为一种具有显著社会效益和经济效益的施工技术。以厦门凤南桥顶升工程项目为例,系统总结了该项目在施工过程中的桥梁顶升技术和工艺,以期为类似工程提供参考。With the development of urban construction,some existing bridges cannot meet the needs of modern cities due to their functional use.However,considering the need to save costs,the main structure of the bridge still needs to be preserved in actual construction.To reduce the generation of construction waste and its impact on traffic during the construction process,the bridge jacking method has become a construction technology with significant social and economic benefits.Taking the Fengnan Bridge jacking project in Xiamen as an example,this article systematically summarizes the bridge jacking technology and process during the construction process,in order to provide reference for similar projects.
