对于高速铁路上桥梁的合理结构形式 ,已有不少学者做了大量科研和计算等实际工作 ,得到了许多有价值的结论。但是他们的研究均是针对直线梁进行的 ,而对曲线梁桥的合理结构形式的研究较少。介绍高速铁路曲线梁桥合理结构形式的一些研究工作和相关结论 ,主要包括支座布置形式和约束方式的影响 For the rational structure of bridges on high-speed railway, many scholars have done a lot of practical work such as scientific research and calculation, and got many valuable conclusions. However, their researches are all aimed at the straight-line beam, but there are few researches on the reasonable structure of the curved beam-bridge. This paper introduces some research work and relevant conclusions about the reasonable structure of the curved girder bridge of high-speed railway, including the influence of the layout of the bearing and the restraint method
