路通过能力。首先，介绍移动闭塞模式下列车通过越江区间的运行方式，信号系统需保证线路正常运营，越江段区间风井之间仅有1列车运行：其次，结合列车运行特点，参考UIC406能力分析方法推算出移动闭赛模式下列车在越江区闻内最小追踪闻隔的计算模型，得出最小道追踪间隔与列车在越江区间中运行速度之间的函数关系：然后，通过对所得的函数进行求导，推算出列车在区间中的最高运行速度、接近速度的取值及对最小追踪间隔的影
响，并求得函数的极小值；最后，通过仿真软件验证计算模型的合理性并提出信号控制列车的优化方案。关键词：轨道交通：最小追踪间隔：越江区间：移动闭塞：闭塞时间

Abstract: To improve railway capacity, this study analyzes methods to decrease the minimum headways between two trains crossing a river tunnel from the perspective of a signal system. First, this paper introduces the running mode of a train passing through the crossing of a river under a moving block. To ensure ventilation in the river-crossing tunnel under normal and accident conditions, the signal system only allows one train to run between the two shafts. Second, adapted to the characteristics of train operations, a model of the headway on which trains in the moving block signal system cross the river was developed based on the UIC406 method for calculating the capacity. The functional relationship between the minimum headway and the trains' running speed in the river-crossing section was obtained. Third, the influence of the trains' maximum running speed and the approaching speed on the minimum headway was derived by differentiating the function, and the minimum value of the function was determined. Finally, the reasonability of the model was validated using a simulation
software, and effective solutions to improve capacity from the signal system perspective were proposed Keywords: urban rail transit; minimum headway; cross-river section; moving block system; blocking time

为保证列车在隧道内运行时正常通风及乘客的生命安全，通风专业在越江隧道两端设有风井，要求隧道内追踪运行的两列车不能同时运行在2个风井之间"]。在地铁建设过程中常常受到土建条件的制约，越江隧道区间内的风井间隔一般较远，此时，列车在越江隧道区间的通过能力受到限制。
对于移动闭塞模式的列车，保证列车在越江隧道行车安全的前提下，对线路的通过能力要求较高，需
