| Abstract: | The newly built intercity railway Changji is parallel line with the existing Changtu Railway and the roadbed foundation treatment is designed to be CFG piles. The geographic position of the construction point, the groundwater level is high and the bearing capacity of surface soil high. Construction process of CFG pile was optimized and the appropriate construction methods and monitoring tools were taken to ensure construction safety, the existing circuit-based stable and the successful completion of the con... |
