Maglev rail transit bridge
The embodiment of the invention discloses a maglev rail transit bridge. The maglev rail transit bridge comprises bridge piers, rails and truss girders. The truss girders are sequentially connected inthe length direction, and each truss girder comprises two bridge decks arranged in a stacked mode in the height direction. Each bridge deck is provided with the corresponding rail; every two adjacenttruss girders are arranged on the bridge piers in a butt joint mode. According to the embodiment of the invention, the space requirement problem of large line spacing of the high-speed train is reduced, and the engineering economy is better by utilizing the characteristics of high rigidity and small external action deformation of the truss girders; the structure is high in environmental adaptability, insensitive to temperature, creep and other natural influences and beneficial to providing good train running conditions.
本发明实施例公开了一种磁浮轨道交通桥梁，包括桥墩、轨道和桁架梁；多个所述桁架梁沿长度方向依次连接，所述桁架梁包括沿高度方向层叠设置的两个桥面；每一所述桥面上分别布置所述轨道；相邻两所述桁架梁对接处置于所述桥墩上。本发明实施例减小了高速列车大线间距的空间需求问题，利用了桁架梁的刚度大、对外部作用变形小的特点，工程经济性较好；该结构环境适应能力强，对温度、徐变等自然影响不敏感，有利于提供良好的列车行驶条件。
