东牙溪大桥主桥设计

Design of Main Bridge of Dongyaxi Bridge

东牙溪大桥主桥是一座50 m+4×80 m+50 m预应力混凝土变截面连续刚构桥。介绍了主桥的设计及构造特点,桥梁上部结构内力、变形分析计算的主要结果,探讨了该桥预拱度的设置方法,可为其它同类桥梁的设计提供参考。

The main bridge of Dongyaxi Bridge is a 50 m+4×80 m+50 m pre-stressed concrete variable cross-section continuous rigid frame bridge. The article introduces the design and construction characteristics of the main bridge, the inner force of bridge superstructure, and the main result of deformation analysis calculation. The article discusses the setting method of bridge camber, which can be referred for the design of the other similar bridges.
