Abstract Research purposes： Effective treating the deep intercalation soft soil foundation of YongTaiWen Railway is very important to the investment control and satisfying the requirements of high standard railway subgrade for stability and control of the post-construction settlement, so the study is done on seeking a foundation reinforcement technique which is feasible in technology and rational in the cost.
Research conclusions：Bag-grouting pile is a new technique integrating stratified grouting technique with geo textile and it can be used for forming composite foundation along with the soil around to improve the rigidity and the bearing capacity of subgrade soil with the features of continuous process, non-contamination and high availability of materials, so it can be used to reinforce the deep intercalation soft soil foundation.
