Abstract

Changsha Maglev line is a low-speed magnetic levitation (Maglev) line for which traffic was opened in late December 2015. The simply-supported guideway beams (SGBs) of this maglev line adopted a rectangular cross-section. Cross beams were used to connect the SGBs for the first time in this bridge. In this paper, relevant design specifications, geometry of the guideway beam and the accelerated construction method are described. The performance of the SGBs was analyzed numerically and verified by a full-scale field test. The new form of the SGBs is found to perform well and to be costefficient.
