矮塔斜拉桥设计要点研究

Study of Low Tower Cable-stayed Bridge Design Features

近年来,由于矮塔斜拉桥在结构受力、施工安装上的优越性,在我国得到了快速发展。矮塔斜拉桥具有以下优点:索塔塔高较低,施工简单;斜拉索应力变化幅度较小,可以充分发挥拉索高强钢筋的材料性能;梁体刚度较大,施工过程及合龙后,不需进行索力调整,施工方便。

In recent years, low tower cable-stayed bridge has been rapid developped in superiority in force structure and construction. The low tower cable-stayed bridge has the China because of its following advantages tower is low and construction is simple; the changes magnitude of cable-stayed stress is small, it can take full advantage of material properties of high-strength steel cable; girder stiffness is large, after the construction process and the closure without the need for adjusting the cable force to facilitate the construction.
