桂林市信义路桥的梁、墩、拱圈连接研究

Study of Connection Among Girder, Piers and ArchRing of Xinyi Road Bridge in Guilin City

应用计算机和光弹性模型试验进行全桥结构仿真分析,研究因美观要求,在Y形墩三跨连续预应力混凝土刚构桥上安装拱圈引起的影响。给出桂林市信义路桥的梁、墩、拱圈附近的应力分布,全桥结构振动模态,为该桥提供技术参考。

A simulation analysis for the overall structure of Xinyi Road Bridge is conducted based on the computer and photoelastic model tests. The influences due to aesthetic requirements upon the installation of arch ring on the 3span continuous prestressed concrete rigidframe bridge on Yshape piers are studied, and the results of stress distribution near the girder, piers, arch ring and structural vibration modes of the Bridge are given as well, which provides reference to the technical decisions for the Bridge.
