Abstract: The consolidation in saturated orthogonal anisotropic soil among group-piles was studied.Considering the initial distribution and the boundary conditions of excess pore water pressure caused by group-piles,the space consolidation model was established and the progression solutions could be found by using methods of mathematical physics in enclosed field.The solutions could give the results of consolidation degree and pore-water pressure at any point at any time.When the initial distribution of pore pressure was constant and the soil was isotropic,the reasonableness of the solutions was proved by the progression solutions,which could be degenerated to Terzaghi’s one-dimensional consolidation solutions.Finally,practical engineering case was presented to illustrate the results and laws of the soil consolidation.
