摘　　要：高速铁路开通运营后,相关平行既有线旅客列车分流,列车运行图结构发生变化,从而影响既有线区间通过能力,同时货运通过能力得以释放。运用直接计算法定量分析列车追踪间隔时间、不同种类列车区间运行时分之差、连发比例等参数的变化对既有线区间通过能力产生的影响;综合运用扣除系数法和直接计算法,以京广高速铁路京石郑段为例,根据高速铁路开通前后旅客列车数量的比较分析,定量计算既有京广线货运通过能力的释放数量。After opening and operation of high-speed railways, the passenger trains of relative parallel existing lines were shunted, and the structure of train diagram was changed, which influencing the section carrying capacity of existing line and releasing the carrying capacity for freight transportation. By using direct calculation method, this paper takes quantitive analysis on the changes of parameters such as the interval time of train tracing, the differences of sectional operation time between different types of trains and the proportion of train dispatching in succession, which bring influences on section carrying capacity of existing line; through comprehensive use of deduction coefficient method and direct calculation method, taking Beijing-Shijiazhuang-Zhengzhou section of Beijing-Guangzhou high-speed railway as example, and based on comparative analysis on passenger train number before and after opening of high-speed railways, the paper takes quantitive calculation on releasing volume of carrying capacity for freight transportation on existing Beijing-Guangzhou line.
