ASYMMETRIC CONSOLIDATION OF MULTI-LAYERED SOILS WITH ANISOTROPIC PERMEABILITY

Starting from the governing equations of asymmetric consolidation of soil with anisotropic permeability,together with the technique of Fourier expansions,Laplace-Hankel transform with respect to coordinate z,time t and coordinate r,respectively,a linear equations in four is obtained,after solving the equations,the transfer matrix for a single soil layer with anisotropic permeability is first acquired.Based on the continuity and the boundary conditions,the transfer matrix method is utilized to derive the solution for the multi-layered soils with anisotropic permeability in the transform domain.By the inversion of the Laplace-Hankel transform,the solution for consolidation problems of multi-layered soils with anisotropic permeability in the physical domain is obtained.Numerical calculation and analysis are carried out by the computer program,and the effect of anisotropic permeability on the process of soil consolidation is also discussed.
