山西中南部铁路是一条新建的万吨重载煤炭运输通道，是国内首条研究30t大轴重万吨列车运行安全的铁路，铁路线路平纵断面、车站分布等的设计，需满足万吨级列车的循环制动与纵向冲动等要求。运用列车纵向动力学仿真软件指导重载铁路的设计，通过对不同机车牵引万吨单编列车的纵向动力学仿真研究，特别是万吨列车在不同坡度坡道上的制动限速、制动距离，以及长大下坡道困难区间操纵运行的安全性和纵向冲动，研究山西中南部铁路壶关至红旗渠段长大坡道缓坡设置问题，以满足万吨重载列车在非正常情况下的运行、养护维修及救援要求。研究结论为：壶关至红旗渠间居中位置应增设缓坡1处，并配备救援设备。研究结论已应用于项目设计，在壶关至红旗渠间增设了平顺站，并设机待线，配备双机重联救援机车。

The Central and Southern Shanxi Railway is a new line for 10 000-ton trains, and the first domestic line on which trains of 30t axle load 10 000-ton are tested. The design of vertical section and stations distribution of this railway has to satisfy the cycle braking and longitudinal impulse of 10 000-ton trains. This paper uses train longitudinal dynamics simulation software to guide the design of heavy haul railway. With simulations of 10 000-ton trains hauled by different locomotives, limited braking speed, braking length, operation safety and longitudinal impulse are analyzed when 10 000-ton trains run on the long downhill slope. Slight gradient of the long downhill slope between Huguan and Hongqiqu is studied so as to meet the requirements of operation, maintenance and rescue under abnormal conditions. Research suggests that one slight gradient shall be added between Huguan and Hongqiqu and rescue equipment provided. The research results have been applied in project design, an additional station is provided between Huguan and Hongqiqu with locomotive waiting track and equipped with double machine reconnection rescue locomotive.
