Nowadays, the high-speed railway CTCS-3 train control system has realized the train tracking operation through the long block section consisting of two sections of track circuits. The train interval is composed of block sections, while the long block section will reduce the resolution of the train interval distance, which limits the carrying capacity of the railway to some extent. In order to reduce the capacity loss caused by long block section, without adding additional hardware equipment, a method to improve the carrying capacity of existing high-speed railway by dynamically combining block section was proposed in this paper. According to the different position of the two track circuits in the same block section, the block section is dynamically combined and the transmission code of the track circuit is dynamically adjusted to shorten the distance of the train tracking interval which improve the carrying capacity. Finally, taking the Beijing-Shanghai high-speed railway as an example, the theoretical analysis and calculation under different scenarios are carried out to verify the safety and effectiveness of the proposed method.

一种提高CTCS-3铁路运载能力的方法

如今，高铁CTCS-3列控系统通过由两段轨道电路组成的长块段实现了列车跟踪运行。列车间隔由块段组成，而较长的块段会降低列车间隔距离的分辨率，在一定程度上限制了铁路的承载能力。为减少长段段造成的运力损失，在不增加额外硬件设备的情况下，提出了一种动态组合段段来提高既有高速铁路承载能力的方法。根据同一街区段内两条轨道线路的不同位置，动态组合块段，动态调整轨道电路的传输码，缩短列车跟踪间隔的距离，提高运载能力。最后，以京沪高铁为例，进行了不同场景下的理论分析和计算，验证了所提方法的安全性和有效性。
