摘　　要：现有各类城市轨道交通(简称“城轨”)线路运行能力计算软件因缺乏统一标准,给城轨工程设计及实施等带来诸多问题。为此,文章基于城轨线路结构特征、列车牵引/制动特性、信号系统性能和运营管理规律,并根据城市轨道交通运输系统工程设计的需求,提出一种城轨线路运行能力计算标准化方案,涉及标准原则、运行能力指标及精度要求、规范化的计算框架、标准化的模型接口以及应用和扩展性。所提出的线路运行能力计算标准化流程和建模方案,方便工程业主及各参与方对城轨系统工程设计方案(如线路设计方案和信号设计方案)所能达到的行车能力进行评估,使得计算结果与方案实施后取得的实际效果偏差在允许的误差范围内,利于各方对工程方案的行车能力状况和优化方向达成共识,以便在工程设计早期优化方案,从而带来效益的提升。Due to the lack of unified standards, the existing software for calculating the operation capacity of various urban rail lines introduces many problems to the design and implementation of urban rail engineering. Based on the full grasp of the structure characteristics of urban rail line, train traction and braking characteristics, signal system performance and operation management law, and according to the requirements of urban rail transit system engineering design, this paper puts forward standardization scheme of urban rail transit line operation capacity calculation, involving standard principles, operation capacity indicators and accuracy requirements, normalized computing framework, standardized model interface, application and scalability. This paper proposes a standardized process and modeling scheme of line operation capacity calculation, which is convenient for the project owner and all participants to evaluate the train operation capacity achieved by the urban rail transit system design scheme(such as line design scheme and signal design scheme), so that the deviation between the calculation results and the actual effect after the implementation of the scheme is within the allowable error range, all parties can reach a consensus on the driving capacity status and optimization direction of the project scheme, so as to optimize the scheme as soon as possible in the early stage of project design and improve benefits.
