Abstract:The vibro-replacement stone pile can form composite foundation by replacing and squeezing the soft foundation. It can increase the soil deformation modulus and bearing capacity,improve the soil inhomogenity,reduce uneven settlement of foundation,and effectively prevent earthquake liquefaction of foundation. Although this method has been widely used,it is generally applied in small range and shallow depth. By using high-power equipment and taking corresponding engineering measures,foundation treatment can be carried out in large range and great depth with vibro-replacement stone effectively under complex condition of engineering geology. The problems of sand liquefaction,bearing capacity and shear strength of foundation can be solved effectively.
