The multi-coupling in the dynamic consolidation method(DCM) for reinforcing foundations is analyzed. Integrated considering factors of liquid
solid
dynamic resulting from rammer bump into ground
the solution method and iterative format are given based on three—dimensional finite element method. Though coupling analysis of an actual project
the variational rule and distributing character on displacement
stress
and contact stress are obtained. The results have shown good agreement with those data of the actual project. The coupling method proposed is applicable to dynamic consolidation method and the similar dynamic questions.
