摘要:
针对城市轨道交通T型换乘站结构特征、主要换乘形式及换乘能力影响因素，分析原换乘能力计算方法存在的问题，探讨了站台可通行宽度及换乘设施实际通过能力对换乘能力取值的影响，提出了基于站台可通行宽度的站台通过能力计算方法，并以此提出了T型换乘站换乘能力测算的新方法；最后以郑州地铁南五里堡站为对象进行案例研究。研究结果表明，相对于原计算方法，新方法大幅度提升了换乘能力计算的准确性。
Abstracts:
Targeting the structural characteristics, main transfer forms and influencing factors of transfer capacity of urban rail transit T-type transfer station, the problems existing in the old transfer capacity calculation methods are analyzed. The influence of the platform passable width and the actual passing capacity of transfer facilities on the transfer capacity is discussed. The calculation method of platform passing capacity based on platform passable width is proposed, on the basis of which, a new method for calculating the transfer capacity of T-type transfer station is proposed. Finally, Nanwulibao Station of Zhengzhou Metro is taken for case research. Results show that compared with the conventional calculation methods, the new method greatly improves the accuracy of transfer capacity calculation.
