摘要
针对我国铁路列车提速后线路结构所出现的突出动力学问题,基于现代车辆-轨道耦合动力学理论分析结果,综合提出了强化提速线路的五项关键配套技术对策;通过线路现场试验、工程实践及实际运营观测,检验了所提技术措施的实际运用效果和现实可行性。提速线路强化配套技术措施的逐步实施,是确保中国铁路提速线路长期、安全、可靠运营并保持低维修成本的根本前提,具有深远意义。
Dynamic surrounding of railway infrastructure has been worsening due to raising train speeds on the existing railway lines in China. On the basis of vehicletrack coupling dynamic analysis results, five key technical measures are brought forward to strengthen the track structure and subgrade of the speedincreased lines. The feasibility and actual effect of these measures are verified by field experiments and practical engineering applications .
