摘要
合安高速铁路花岗特大桥是合安高速铁路工程的一部分,为预应力混凝土连续梁与钢管混凝土拱组合结构,横向为单箱双室箱形截面。本桥全长361.6 m,桥面宽14.2 m。根据横向受力方式的不同,将计算分析分为普通截面和吊杆截面,采用有限元设计软件桥梁博士对普通截面和吊杆截面进行横向受力分析,根据计算结果进行配筋及截面设计优化。
Granite Bridge of He'an High Speed Railway is a part of He'an High-speed Railway Project.It is a composite structure of pre-stressed concrete continuous beam and concrete filled steel tube arch,with transverse single box and double chamber box section.The bridge is 361.6m in length and 14.2 m in width.According to the different ways of transverse force,the calculation and analysis are divided into ordinary section and suspender section.In this chapter,the finite element design software Dr.Bridge is used to analyze the transverse force of ordinary section and suspender section,and the reinforcement and section design are optimized according to the calculation results.
