曲线梁桥的工程设计方法研究

Study on Design Method of Curve Beam Bridge Engineering

现有的桥梁规范并不能很好地适用于曲线梁桥的全面设计,这在一定程度上使得设计曲线梁桥存在着一些困难。文中以实际设计的曲线梁桥为例,从跨径和截面选择、支座预留偏心、支承约束、总体布置等方面进行计算和分析,最终所得到的应力与曲线梁桥受力特性一致。

The existing bridge specification is not very well suitable for curved girder＇s overall design, so there are some difficulties in the design of curve Beam Bridge. Based on the actual design of curve beam bridge as an example, from the following several aspects including the selection, cross section selection, bearing eccentricity, and overall arrangement and so on, the calculation and analysis of curved girder were carried out. Finally the stress of the bridge was calculated which is highly consist- ent with the load-bearing characteristics of curve beam bridge.
