The utility model discloses a pile for treatment of low embankment, railway soft soil foundation including composite foundation in embankment core stress area, the embankment core stress zone for ballastless track on both sides of the support layer 45 degrees below the regional diffusion angle range of the composite foundation are arranged on the top surface of the gravel cushion the middle of the gravel cushion, with geogrid, embankment is located in the core force in a bored pile, the bored pile top is provided with a reinforced concrete continuous beam plate. The utility model in the core stress zone in the embankment with bored piles and reinforced concrete continuous beam and thin plate in the bored pile top, solved due to some deep soft soil section affected by external factors to set the bridge, resulting in foundation treatment of conventional methods can not satisfy the settlement of ballastless track the control requirements and to ensure the stability of Subgrade under train load long-term problems. It is suitable for the treatment of deep soft soil foundation of high speed railway.
