城市轨道交通互联互通车站配线设计及能力计算

互联互通是城市轨道交通发展的趋势,互联互通车站是实现不同线路间互联互通必不可少的关键节点。互联互通车站按照联通方向数量可分为Y型车站和X型车站,并分别设计其配线形式。运用列车模拟牵引计算和图解法,计算不同车站形式下的列车通过能力,并从车站规模、行车安全性、客流组织、通过能力等方面进行对比分析。研究表明,一岛一侧Y型车站相比双岛四线Y型车站规模较小,系统通过能力可达到30对/h;相比双岛四线X型车站,四岛八线X型车站在行车组织、客流组织、通过能力方面均具有明显优势,缺点是车站规模大。

Design and Capacity Calculation of Inter-connected Station in Urban Rail Transit

An inter-connected operation is under development in urban rail transit, and an inter-connected station is a key node to realize connectivity among different lines. The stations were divided into two types, Y- and X-type stations, according to the inter-connection method. The design of the track layout in the inter-connected stations was adequately discussed, and the carrying capacity of these stations was calculated through train traction calculations and a graphical method. In addition, the merits and disadvantages of each scheme were pointed out regarding the size of the stations, operation safety, passenger flow organization, and the carrying capacity. The results show that a one-island-one-side with three lines Y-type station is smaller than a two-island with four lines X-type station, and a capacity of up to 30 pairs/h can be attained; compared with three two-island with four lines X-type stations, a four-island with eight lines X-type station has clear advantages in terms of train operation management, passenger flow organization, and the carrying capacity, but is more costly.
