摘　　要：用战备多用途浮箱和八三轻墩组成浮体,在水上利用潮差采用浮运法对既有桥钢板梁进行拆除施工,工序简便快捷,所用的机械设备投入少,可以大大提高施工速度。结合甬台温铁路奉化江大桥施工实例,阐述了多用途浮箱浮体的设计与施工技术。Floating body composed of utility pontoons for war preparedness and military railway bridge piers can be used in steel bridge erection and backout. The construction process is improved and input of the mechanical equipment is reduced with this floating structure, also, the construction speed is increased dramatically. In the light of the construction of Feng huajiang bridge on Yongtaiwen railway, this paper introduces the design and construction of the floating structure with utility pontoon.
