Abstract
An individual vacuum consolidation system has gained a popularity for a ground improvement of soft clayey soil. Finite element anaylses have been performed to simulate the individual vacuum consolidation system using a Plaxis 2D. The modelling procedures of the vacuum consolidation system are presented with the results of an unit-cell analysis. In addition, a case study was carried out to assess the applicability of the Plaxis 2D for simulating the consolidation behavior of soft ground subjected to the individual vacuum pressure.
