Three Dimensional Consolidation and Numerical Simulation Consdering Initial Slope Seepage

In the report,non-Darcy law was introduced into Biot three-dimensional consolidation equation of saturated soils,three-dimensional gradient consolidation equation considering starting gradient ratio was deduced.Space eight-node isoparametric element was used to obtain the three-dimensional consolidation numerical equation considering starting gradient ratio,on which the finite element seepage model was constructed. The model reflected the initial slope of the dissipation of pore water pressure and average consolidation degree very well,and the results are agreement with that of literature[8].
