摘　　要：不同层次轨道交通间的直通运营具有减少乘客出行时间、节约土地资源等优势。该模式下,在直通区段上运行的不同层次或不同技术标准(如速度目标值、车辆制式等)的列车互称为异质列车。在分析车站追踪间隔计算原理及方法的基础上,将组合周期时间作为计算直通区段通过能力的主要依据,建立了直通区段通过能力计算模型,并运用回归分析方法得到不同站间距下列车速度目标值与旅行速度的相关关系。研究表明:直通区段通过能力与异质列车的速度目标值组合具有相关性。在部分参数取值给定的条件下,随着两种异质列车速度目标值差值的增大,直通区段通过能力有所减小。Rail transit through-operation at different levels features passenger travel time reduction and land resource saving.In this mode,trains with different operation levels or different technical standards(such as speed target value,vehicle systems)running in the through-section are called heterogeneous trains.Through analyzing the calculation principle and method of station tracking interval,the combined cycle time is taken as the main basis for calculating the carrying capacity in through-section,and the calculation model of through-section carrying capacity is established.The relation between speed target value and travelling speed with different station spacing is inferred by applying regression analysis method.The study shows that the carrying capacity in through-section is related to the combination of heterogeneous train speed target values.Under the condition that some parameter values are given,as the difference between the speed target values of two heterogeneous trains increases,the carrying capacity in through-section would decrease.
