介绍了重庆菜园坝长江大桥主桥轻轨钢轨道梁检修走道的设计。设计采用较简单的构件组合满足了并不单一的功能要求,合理地适应了列车限界、轨道梁、主桁结构在空间位置上对它的限制,制作和安装也比较简便。 The design of the light rail track beam access aisle of the main bridge of Chongqing Caiyuanba Yangtze River Bridge is introduced. The design uses a relatively simple combination of components to meet the functional requirements that are not unique, and reasonably adapts to the limitation of the limit of the train, the track beam and the main truss structure in the spatial position, and the manufacture and installation are relatively simple.
