铁路节段预制胶接拼装法建造桥梁技术与应用

Application and Technology of Precast Segments Cementing Assembling Bridges on Railways

节段预制胶接拼装法造桥是分段建造桥梁的一种,在原理上是预应力结构、箱梁设计和分段施工法综合而成,经济技术性强,适用范围广。结合国内首座采用节段预制胶拼法建造的铁路桥梁工程实例,从节段预制胶接拼装造桥基本理论入手,对节段预制技术、胶接拼装装备、胶接拼装技术进行了叙述,以期对其他节段预制胶接拼装法建造桥梁工程提供借鉴。

The precast segments cementing assembling bridge-building is one kind of segmented bridge building methods, integrated from the prestressed structures,box girder design and segmented construction method in principle,which boasts the advantages of advanced technology and a wide range of application.Combined with the first precast segments cementing assembling bridges for railways the paper explores and analyzes precast segmental technology,segment assembly equip-ment,segment assembly technology,in order to provide reference to the other engineering from the theory of precast seg-ments cementing assembling bridge-building basic.
