双层桥面钢桁腹PC组合桥梁设计与建造方法分析
|
摘要
伴随当前我国道路桥梁工程技术发展速度不断的提升,在进行桥梁设计过程当中,采用的是全新的桥面设计方式,这种设计方式可以实现桥梁双层桥面钢桁腹预应力混凝土的组合性桥梁结构,通过这种设计方式,可以提高桥梁整体的安全性和稳定性,在最近几年的发展过程当中,受到了人们广泛的关注。本文通过某具体桥梁工程施工实例来进行分析,重点对双层桥面钢桁腹PC组合桥梁设计及其建造方法进行了有效的分析,希望对我国桥梁工程建设发展提供借鉴。
With the continuous improvement of the development speed of road and bridge engineering technology in China, in the process of bridge design, a new bridge deck design method is adopted. This design method can realize the combined bridge structure of steel double-decked bridge steel prestressed concrete. Through this design, the safety and stability of the bridge can be improved as a whole,and it has received extensive attention in the development process in recent years. This paper analyzes the construction example of a specific bridge project, and focuses on the effective analysis of the design and construction method of double-deck bridge steel-belly PC combined bridge. It is hoped to provide reference for the development of bridge engineering in China.
