Nonlinear Consolidation Nonlinear Consolidation Analysis of Dredged and Reclaimed Ground with The Lateral Drain Vacuum Consolidation Method

摘要

In applying vacuum consolidation method using horizontal drain torndredged and reclaimed soft ground;;nonlinear finite consolidationrnphenomenon takes place. In this paper;;Governing equation wasrnmodified to consider these phenomenon and nonlinear materialrnfunction(effective stress-void ratio-permeability relationship) was determinedrnwith slurry consolidometer and analysis program was developedrnusing above result. From the modeling of pilot test;;material functionrnoverestimate 37% in compressibility and underestimate 3.5times inrnpermeability. Design parameter were analyzed Using the analysis programrnand effective arrangement of drain was determined.
