One-Dimensional Nonlinear Consolidation for Soft Clays with Continuous Drainage Boundary Considering Non-Darcy Flow

Adopting the non-Darcy flow presented by Hansbo and considering nonlinear compression permeability characteristics of soils, one-dimensional consolidation problem soft clays is investigated means a continuous drainage boundary. The numerical solutions average degrees defined settlement excess pore water pressure are derived using finite difference method, correctness these verified comparing them with existing analytical solutions. Based on proposed solutions, parametric study conducted to influence interface parameter, parameter soil nonlinearity behavior clays. results show that based boundary can be degenerated into Terzaghi if taken as reasonable value. both seepage very complex.
