SEMI-ANALYTICAL SOLUTION FOR ONE-DIMENSIONAL CONSOLIDATION OF LAYERED-SOIL WITH NON-DARCIAN FLOW

Based on the non-Darcian flow law proposed by Hansbo in layered-soil, the numerical solutions for one-dimensional consolidation of layered-soil was obtained under time-dependent loading by a semi-analytical method. The reliability of the semi-analytical solution for one-dimensional consolidation of layered-soil with non-Darcian flow was verified by comparing the results of double-layered soil with non-Darcian flow law by semi-analytical method with that by finite difference method. Finally, a calculation case of one-dimensional consolidation of triple-layered soil with non-Darcian flow law was analyzed. The results show that the rate of excess pore water pressure dissipation is different from that of the settlement during the consolidation of layered-soil with non-Darcian flow.
