摘要
研究目的:重载铁路因其运量多、轴重大,大大加剧了轨道结构的伤损,给轨道结构提出了严格要求。本文从国内外重载铁路运输发展入手,在深入总结、分析国内外重载铁路轨道结构现状及存在问题基础上,提出了国内重载铁路轨道技术发展方向的建议,以期对国内重载铁路轨道技术研究提供有益参考。研究结论:重载铁路是一个系统工程,研究过程中应遵循轨道子系统与其他子系统研究并重、理论研究与试验研究并重、新型轨道部件研制与新型养修设备研制并重的原则;高度重视结构理论研究;积极推进新型轨道结构研发及新型轨道部件研制;加强重载铁路轨道检测与养护维修技术研究;加快研制多品种、专业化的大型养路机械。
Research purposes： As the traffic volume of heavy - haul railway is big and the axle load of the train running on heavy haul railway is heavy, the damage of the track structure of heavy - haul railway is much intensified, so the higher requirement is needed for the track structure of the heavy - haul railway. Starting with the developments of the heavy -haul railways at home and aboard, after summing up and analyzing the current situations and existing problems of the track structure of the heavy - haul railway at home and aboard, this paper offers the advices on the development direction of the track technology of the heavy - haul railway for providing the reference to the research on the track technology of heavy - haul railway at home and abroad. Research conclusions：The heavy haul railway is a system engineering, so in the research the following principles should be followed： the equal stress should be laid on the track subsystem and other subsystem, on the theoretical research and experiment research, and on the new track component research and new maintenance equipment research. Especially, the structure theoretical research must be stressed, the new track structure research and new track components research should be promoted, the detection and maintenance technologies of the track of heavy - haul railway should be strengthened, and the development of professional large - sized permanent way maintenance machine should be speeded up.
