- Abstract:
- The Hansbo’s formula for non-Darcy flow :. introduced to modify Terzaghi’s 1-D consolidation e.quation, and the modified equation is generalized to account for the consolidation case under time-dependentconstruction loadings. The dependent variable of the presented nonlinear consolidation equation is the effectivestress, and numerical analysis is performed by using the finite volume method. "Then the effects of the parame.ters of Hansbo flow and the rate of loading on the 1-D consolidation behaviors of saturated clay layers are in.vestigated. The numerical results indicate that Hansbo flow causes the more accumulation of the pore waterpressure in the construction period and delays its dissipation after construction, and the rate of setlement ofthe soil layer deereases with the inerease of the parameters of Hansbo flow, In addition, the influence of load.ing rate on the consolidation behaviors is remarkable in the construction period and at the initial stage after itseompletion of construiction.
