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.
