| Abstract: | Qinshen rail line is the first railway built specially for passengers in our country. Because of the high speed of the trains running on this rail the dynamic stress and vibration acceleration in subgrade are of vital importance for subgrade design. For this puropose, field testing was carried out to determine the dynamic stress and vibration acceleration in subgrade with 40cm and 60cm in depth. The results are analysed and the distribution of the stress and acceleration along the subgrade transect and depth are provided. The relation between train speed and dynamic performance of subgrade is also discussed. |
