某中低速磁浮试验线桥梁总体设计

依托某中低速磁浮试验线工程,以进一步提高中低速磁浮桥梁的经济性、施工便捷性及中低速磁浮交通与跨座式单轨等新型轨道交通的竞争优势为目的,重点阐述中低速磁浮轨道梁结构体系、墩梁型、经济跨度及施工方法的比选,并结合磁浮车辆独特的走行方式对桥面布置、桥上设备安装及管线敷设方式进行优化。根据中低速磁浮线路运营安全性及行驶舒适性的要求,在既有磁浮桥梁技术标准体系研究成果的基础上,提出推荐的轨道梁结构形式及施工方法。

General Bridge Design of Medium and Low Speed Magnetic Levitation Test Line

In order to reduce the cost and difficulties of bridge construction for medium and low speed maglev projects and make it more competitive over straddle type monorail, this paper addresses the selection of track beam structural system, beam and pier types, economical span and construction method based on a test line project of medium and low speed maglev. Bridge deck layout, equipment installation and pipeline arrangements are optimized in consideration of the unique running manner of maglev vehicles. This paper provides an optimized track beam structural system and its construction method based on the requirements for safe and comfort operation, and existing design codes and standards.
