One-dimensional consolidation of layered and visco-elastic soils under arbitrary loading

Based on the layered visco-elastic soil model, according to the Terzaghi's one dimensional consolidation theory, by the method of Laplace transform an d matrix transfer technique, the problems about the consolidation of layere d and saturated visco-elastic soils under arbitrary loading were solved. Th rough deductions, the general solution, in the terms of layer thickness, th e modulus and the coefficients of permeability and Laplacian transform's pa rameters was obtained. The strain and deformation of the layered and satura ted visco-elastic soils under arbitrary loading can be calculated by Laplac e inversion. According to the results of several numerical examples, the co nsolidation of visco-elastic soils logs behind that of elastic soils. The d evelopment of effective stress and the displacement is vibrant process unde r cyclic loading. Finally, an engineering case is studied and the results p rove that the methods are very effective.
