One-Dimensional Consolidation of Saturated Clays under Time-Dependent Loadings Considering Non-Darcy Flow
Hansbo's formula for non-Darcy flow was introduced to modify Terzaghi's 1-D consolidation equation, and the modified equation was generalized to account for the consolidation case under time-dependent loading. Numerical analysis was performed by using the finite volume method. The effects of the parameters of non-Darcy flow and the rate of loading on the consolidation process were investigated. The numerical results indicated that non-Darcy flow delays the dissipation of pore water pressure in saturated clay layers; thereby the rate of settlement of these soil layers is less than the solution based on Darcy flow. In addition, the influence of loading rate on the consolidation behaviors is remarkable in the construction period and in the initial stage after its completion of construction.
