Abstract: The vibro replacement stone piles are widely used in engineering and various problems have been studied in different depth. Based on the soft soil foundation treatment of vibro replacement stone pile, combined with super heavy dynamic penetration test,dynamic penetration test results, we can get parameters and we can know that vibro replacement stone piles deal with soft foundation can improve the foundation bearing capacity of composite foundation, modulus of deformation and reduce settlement. Engineering practice shows that the method of soft foundation treatment with economic reasonable, convenient construction, fully meet the design requirements and can be widely used.
