为研究不同运输组织模式下京沪高速铁路区段通过能力问题，本文首先分析了列车铺画方式对通过能力的影响.通过对比分析可知，将停站次数相同的列车成组铺画能够提高通过能力.在此思路基础上分别给出了停站高速列车和中速列车成组铺画方式下的扣除系数计算公式.运用该扣除系数，进一步分别计算了京沪高速铁路在全高速运输组织模式下和高中混跑运输组织模式下的通过能力，并对通过能力的影响因素进行了深入分析.

Carrying Capacity of Beijing-Shanghai High-Speed Railway by Different Transport Organization Patterns

This paper focuses on the Beijing-Shanghai High-Speed Railway(HSR) carrying capacity with different transport organization patterns.First,it presents the relationship between train combination pattern and carrying capacity.By comparing the reduction coefficient of two train combination patterns,it can be found that the carrying capacity can be improved by forming the pattern of trains with the same intermediate stop times tracing each other in a group.Based on that,the paper develops the reduction coefficient calculation formulas of both the high-speed and middle-speed trains.Using the obtained reduction coefficients,the paper then calculates the carrying capacity of Beijing-Shanghai HSR with different transport organization patterns.In the last section,it deeply analyzes the influencing factors of high-speed railway carrying capacity.
