摘　　要：悬浮式施工便桥是将钢栈桥和浮桥、悬浮隧道等工程的特点相结合的一种新型梁桥。它依靠其主体结构——悬浮体结构在水中所受到的水浮力,承载桥梁自重及荷载,从而达到平衡。悬浮体结构是一种新型离散式浮桥基础结构。本文对悬浮体结构的重要组成部分——浮筒,在静水压力作用下的变形,进行了初步的分析。同时对悬浮体结构进行了初步的设计,并简单地分析了其力学特性。Floating temporary construction bridge is a new type of girder bridge that combines the characteristics of steel trestle bridges,floating bridges,and submerged floating tunnels.It relies on its main structure-the floating structure in the water to carry the dead weight and load to achieve balance.Floating structure is a new type of discrete floating bridge basic structure.This paper makes a preliminary analysis on the deformation of the pontoon,an important part of the floating structure,under the action of hydrostatic pressure.A preliminary design of the floating structure is carried out,and its mechanical properties are simply analyzed.
