IMPACT OF RAIL TRAFFIC VIBRATION ON ANALYSIS OF CFG PILE COMPOSITE FOUNDATION

The impact of urban rail transit operating vibration of the building along with its rapid development has affected greatly valued. However, the current study is are mostly concentrated in the building structure. CFG pile composite foundation for less impact studies. This paper analyzed the two subway vibration on the impact of CFG pile composite foundation. And we also used FLAC-3D to analyze evaluation methods and speed of CFG pile deformation caused by the subway vibration changes. This result provides a basis for the evaluation of vibration impact on foundation.
