扭环线型地铁

On the Torsion-ring Alignment Subway

扭环线型地铁,为解决正在规划拟建的城轨线路在主城区的线网密度太低,而在总体城轨规划中线路的长度太长、投资太大的问题提供了一种新的线型方案。在一条有上下行双线的地铁运营线路上至少有一个通过线路自身的扭转形成的环型,在这个环型上至少有一个线路自身的、上下分离立体交叉的换乘车站。用主城区的扭环线型地铁与郊区的并联高架路相配合组成大城市的骨干公共交通网。

The torsion-ring subway can provide a new alignment scheme,it will solve the problems such as the low network density of the proposed urban rail line in the main city area,the excess length and large investment in the overall planning of urban rail transit.In the scheme,there is at least one ring formed by line torsion on a double-line subway operation line,and at least one transfer station with separated up line and down line on this ring.The cooperation of the torsion-ring subway in the main city area and the parallel elevated road in the suburban areas will form the main public traffic network for big cities.
