浅谈中承式拱桥的设计

Elementary Discussion on Design of Half-through Arch Bridge

拱桥结构型式美观,素有"彩虹桥"的美称。上跨高速公路的拱桥给高速公路的行车增加了美好的视觉效果,在高速公路建设中有很多成功的例子,施工技术较成熟。该文通过某上跨高速公路的中承式吊杆拱桥的设计,讨论了中承式拱桥的构造、设计计算方法,以供借鉴参考。

The structural shape of the arch bridge is beautiful, being 'Rainbow Bridge'. The arch bridge overpassing the expressways gives the magnificent visual result to the driving on the expressways. There are many successful examples in the construction of the expressways. The construction techniques are well-considered. Through the design of a half-through suspender arch bridge overpassing the expressway, the article discusses the structure and the design calculation method of the half-through arch bridge to be for reference.
