Numerical modelling of soft soil improvement using wick drains

Large-scale tank consolidation experiments are conducted in laboratory and simulated using a porefluid and stress coupling finite element method. Porous elastic and modified critical state plasticity model are used in the simulation to understand the mechanics of wick drain in improving soil consolidation. The numerical study improves the understanding of the effects of onion ring and smear effects on the soft soil settlement during consolidation using wick drains.
