浅谈预应力混凝土宽桥设计

Elementary Discussion on Design of Pre-stressed Concrete Wide Bridge

根据国家"十一五"发展规划昆明新机场明确定为迁建工程,定位为"面向南亚、东南亚,连接欧亚的大型门户枢纽机场",是云南省机场布局和航空网络的核心。离港层主桥是昆明新机场航站楼楼前桥梁工程的重要组成部分,其特点是桥宽较宽,梁高由横向计算控制,结合工程实例,总结设计中的相关经验与体会,简要介绍了宽桥的设计方法,阐述了结构计算的思路,为今后类似工程的设计工作提供了经验和可靠的参考。

According to the National the Eleventh Five-Year Development Plan, the new airport of Kunming is determined as the relocation project, is orientated as the 'large gateway hub airport facing the South Asia and the Southeast Asia, and linking up with the Eurasian, and is the core of airport layout and aviation network of Yunnan Province. The main bridge of the departure floor is the important component of the front bridge project of the terminal building of Kunming International Airport. Its characteristic is the wider bridge.The beam height is controlled by the transverse calculation. Combined with the engineering cases, the article sums up the relative experience in the design, briefly introduces the design method of wide bridge, and sets forth the general concept of structural calculation, which can provide the experience and reliable reference for the design of the similar projects.
