One-dimensional large strain nonlinear thaw consolidation model for saturated frozen soil
Abstract Based on the piece-linear finite difference approach, a one-dimensional large strain thaw consolidation model, TCS1, for saturated frozen soil was established. The model couples the heat transfer considering phase change of pore ice with consolidation deformation, and accounts for large strain, soil self-weight, unfrozen water, variable hydraulic conductivity and compressibility, flexible boundary conditions and time-dependent loading during the process of thaw consolidation. The FORTRAN is used to implement computation of the model. TCS1 was verified by the existing numerical solutions and laboratory tests. The results were in good agreement with the large strain numerical solutions and tests results. Computational examples were conducted for further study of the influence of strain value, loading types and periodic temperature boundaries on the thaw consolidation of frozen soil.
