摘要
根据南京地铁1号线高架结构梁轨设计的需要,进行桥梁与轨道相互作用的专题研究,提出优化的线路设计参数和连续梁无缝线路纵向力的计算方法,以及桥墩水平线刚度的取值,使高架桥结构的梁轨结构设计更加匹配、协调和经济合理,实现总体优化。
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
