高速铁路1.5～10m波段轨道几何不平顺控制标准
Control standards for track geometry irregularity in the 1.5-10 m wavelength band of high-speed railways
摘要
Abstract
To strength the control of track geometry irregularity in the intermediate wavelength band during the operation period of high-speed railway,improve the full-cycle management system for track smoothness,and clarify the coupling relationship between track irregularity excitation and vehicle dynamic response,a management method for track irregularity within the 1.5-10 m band is proposed based on running safety.Based on statistical analysis of field measurements and vehicle-track coupling dynamic simulation,the recommended management values for allowable deviation of track dynamic geometric irregularity in the 1.5-10 m range are provided for different speed levels.Additionally,to facilitate on-site maintenance and repair work,considering the transfer functions between chord lengths and wavelengths as well as the difference between static and dynamic track irregularity,recommended allowable deviation values for track static geometric irregularity using the 5 m mid-chord measurement method are also presented.The results show that:for railway lines operating at 200-250 km·h-1,the recommended values for dynamic longitudinal level irregularity are 3,4,6 and 7 mm,respectively,and for alignment are 3,4,5 and 6 mm;for railway lines operating at 250(exclusive)-350 km·h-1,the values are 2,3,5 and 6 mm for longitudinal level and 2,3,4 and 5 mm for alignment;for railway lines operating at 350(exclusive)-400 km·h-1,the values are 2,3,4,and 5 mm for longitudinal level,with alignment values matching those for 250(exclusive)-350 km·h-1 railway lines.For static geometric track irregularities measured using the 5 m short chord method,the recommended values for routine maintenance,scheduled maintenance,temporary repairs,and speed restriction management are:for 200-250 km·h-1 railway lines,3,4,6 and 7 mm for static longitudinal level irregularity and 3,4,5,and 6 mm for alignment;for 250(exclusive)-350 km·h-1 railway lines,2,3,5 and 6 mm for longitudinal level and 2,3,4 and 5 mm for alignment;for 350(exclusive)-400 km·h-1 railway lines,2,3,4 and 5 mm for longitudinal level,with alignment values identical to those for 250(exclusive)-350 km·h-1 railway lines.关键词
