Abstract:Research purposes: The test was done to the resistance of the ballast bed for the II—type sleeper and the resistant parameters were offered in the past.But with large—scale construction of high—speed railway and continuous speed—raise of the existing lines in China,the III—type concrete sleeper has been widely used in ballast track.Meantime,the cross—section size of ballast bed,ballast material and grain gradation have been continually strengthened and improved.To determine the track resistance of the ballast bed forⅢ一type concrete sleeper is an importantly basic work to design the ballast jointless track.
Research conclusions: Through doing the in—situ tests and making statistic analysis of the tested data for Yunmeng experimental section of the additional second track of Wuhan—Xiangfan Railway,the fitting curves of the ballast longitudinal and lateral resistance of the ballast bed for the III—type concrete sleeper were determined.Besides,the equivalent lateral resisitanee of ballast bed for the III—type concrete sleeper Was calculated.The results could be as the referances to design of the resistance of the jointless track.
