摘要:
本文旨在研究全高速模式下基于扣除系数法的400km／h高速铁路的通过能力计算方法。首先，对不同运行图铺画方式下的扣除系数进行了深入分析，并确定了其计算方法。在群组中列车数量一定的情况下，停站数量较少时按停站列车成组铺画不越行，扣除系数较小；停站数量较多时按成组不停站列车越行停站列车铺画，扣除系数较小。然后，进一步提出了基于扣除系数法的通过能力计算方法，并对影响通过能力的主要因素进行了敏感性分析。结果显示，区间追踪间隔时间的变化对通过能力的影响最为显著。此外，本文还探讨了扣除系数与400km／h高速铁路列车和线路间的内在联系，并通过构造算例，验证了计算方法的正确性和有效性。这一研究为提高高速铁路的运营效率提供了理论支持和实践指导。
Abstract:
This paper aims to study the method for calculating the carrying capacity of 400 km／h high-speed railway under the full high-speed mode based on the deduction coefficient method. Firstly，an in-depth analysis was conducted on the deduction coefficients under different train operation diagramming methods，and their calculation method was determined. When the number of trains in a group was fixed，a smaller deduction coefficient was obtained if fewer stops were involved and block trains were diagrammed without overtaking，while a smaller deduction coefficient was achieved through overtaking of stop trains by non-stop trains if there were many stops. Furthermore，a method for calculating the carrying capacity based on the deduction coefficient method was proposed，and a sensitivity analysis of the main coefficients affecting the carrying capacity was carried out. The results show that the change of section tracking interval time has the most significant impact on the carrying capacity. Moreover，this paper explored the intrinsic relationship between the deduction coefficient and 400 km／h high-speed railway trains and lines，and validated the correctness and effectiveness of the calculation method through constructed examples，providing theoretical support and practical guidance for improving the operational efficiency of high-speed railways.
