Abstract

Abstract

There is a local large deformation in the peripheral foundation soil of the compacting spots,so the mechanical derivation of infinitesimal strain can't eliminate the effect of a rigid displacement,and the large deformation theory must be used to analyze the impact course of dynamic consolidation to foundation soil.The improved artificial boundary conditions are applied to simulate waves propagation at the boundary.Liquefaction element is used in the calculation program for ensuring the mesh stability of the model.Finally,an engineering example is discussed to verify the reliability of this model.
