Abstract

Abstract: Many scholars have been studied the reasonable str uc tural form of bridge in high-speed railway and got a lot of valuable conclusion s.But most of their work are focused on the straight girder bridges.In this pape r we discuss the reasonable structural form about curved girder bridges in high -speed railway.

Key words: curved-girder, reasonable bearing form, restriction conditions

摘要： 对于高速铁路上桥梁的支座布置形式,已有不少学者,做了大量的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研究的,而对曲线梁桥的支座布置形式的研究较少.本文讲述的是高速铁路曲线梁桥支座布置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

关键词: 曲线梁, 合理结构形式, 约束方式
