摘  要：该文通过对固定、移动闭塞模型折返能力的分析，得出移动闭塞折返较固定闭塞有较大提高，具备实现折返间隔90 s可能性，进而实现移动闭塞下达到40对/h行车能力目标。采用高密度组织列车运行，有利于缩短行车间隔，也减少乘客候车时间，提高服务质量。

Abstract： In this paper， through the analysis of the return ability of the fixed and mobile block model， it is concluded that the return of the mobile block is much higher than that of the fixed block， and it is possible to realize the return interval of 90 s， and then achieve the goal of 40 pairs/h driving capacity under the moving block. The use of high-density organization of train operation is beneficial to shorten the running interval， reduce the waiting time of passengers and improve the quality of service.
