Application of CFG Pile Plate Composite Structure in High Speed Railway Soft Foundation

CFG pile plate composite structure is a new kind of soft foundation reinforcement structure, and is gradually promoted in the high speed railway construction. In this paper, combined with the foundation characteristics of Harbin-Dalian passenger dedicated railway worksite, through a large number of experimental data, it is proved that the pile composite foundation plate structure can effectively decrease the uneven settlement of foundation, and adjust pile soil stress distribution. This article mainly expounds the construction process control process and quality control points, and provides reference and reference for soft foundation treatment of passenger dedicated line.
