Preliminary Study on Subgrade Bed Diseases along a Railway in the Northeast and the Reinforcement Measures for Speed-raising |
| |
| Abstract: | A railway in the Northeast, after capacity expansion and reformation engineering, could speed up to 160 km/h. There have relatively serious subgrade diseases on the existing line, hence large range of disease treatment and subgrade reinforcement was required. By the investigation of the existing lines past and current situation and the analysis of the diseases causes, preliminary study was made in relation to the standard of subgrade bearing capacity so as to have a subgrade bed reinforcement scheme economic and reasonable. |
