摘要
重载铁路运输品类为大宗货物,其牵引质量大、轴重大,重载铁路速度目标值的确定有别于普通货运铁路,需要深入探讨。从行车组织、路基、桥梁、轨道、供电等方面,对重载铁路速度目标值为80、100、120 km/h时分别进行计算和对比,并结合国内外运营实际进行分析。对比分析表明,不同速度目标值对轨道、路基、桥梁、供电等影响不大,但当速度目标值大于100 km/h时,机车牵引和制动难以实现,重载货物列车设计行车速度等于或小于100km/h是适宜的。
Heavy-haul railway with large tractive tonnage and big axle load serves to carry bulk cargo and its target speed differs that of conventional freight railway. This paper conducts the calculation and comparison of 80, 100 and 120 km/h target speed respectively in terms of traffic organization, subgrade, bridge, track and power supply, and analysis is made based on operation practices at home and abroad. The results show that different target speeds pose little impact on the track, subgrade, bridge and power supply, but locomotive traction and braking can be hardly fulfilled when speed exceeds 100 km/h. Thus, the running speed of heavy haul train is expected to be 100 km/h and less.
