| |
| Abstract: | In relation to the subgrade settlement disease coming out in certain section of Lanzhou-Xinjiang High-speed Railway, the settlement reasons were analyzed according to the field investigation and data analysis. The comprehensive control measures, including sleeve-valve-pipe grouting, water retaining wall, loading berm and permeable blind ditch, were carried out at the lower part and bottom of the subgrade, and then the control effect was evaluated. The result shows that the subgrade settlement was under control with the control ends achieved. |
