| Abstract: | In this paper, The author introduce the investigations and the dynamic measurements of Da- Qin Railways track structure. Problems discussed are: side wear and plastic failure of the rail, variation of the vertical loads,lateral force and displacement of the track,the stiffness of-the track structure, track vibration, accumulative settlements of the ballast and formation, accumulative settlements of the ballast and its variation with depth and in longitudinal direction, the effects of traffic velocity on dynamic stress, and formation vibration. |
