结合我国既有铁路桥梁及车辆装备现状,分析铁路超重货物运输的制约因素主要是既有桥梁设计标准偏低和早期特种车辆设计较少考虑过桥性能两个方面。针对铁路超重货物运输的发展,在提高货车装备水平的基础上,建议在提高桥梁承载能力、优化车辆设计、铁路特种车辆与大型设备相匹配和加强桥梁日常安全管理等方面综合改善超重货物运输条件。 Combining with the existing railway bridge and vehicle equipment in our country, the main factors that restrict the transportation of overweight railway are the low design standards of existing bridges and the less consideration of bridge performance in early special vehicles design. Aiming at the development of railway overweight cargo transportation, on the basis of improving the level of truck equipment, it is suggested to comprehensively improve the transportation conditions of overweight cargo by improving the bearing capacity of the bridge, optimizing the vehicle design, matching the railway special vehicle with large equipment and strengthening the daily safety management of the bridge .
