| Abstract: | In order to meet the design requirement on beam and track of elevated structure of Nanjing metro line 1, the interaction between the bridge and the track is specially researched. Furthermore, the optimized design parameters of the rail, the calculation method of longitudinal force of CWR based on continuous beam theory, and the selection of horizontal stiffness of the pier are presented, which will make the design of beam and track structure of elevated bridge match better, cooperate better and be more economical to achieve the optimization for the whole de, ion |
