ABSTRACT
In offshore reclamation works using dredged soil containing soft soil with high water content ratio, consolidation settlement of the ground is the main problem. In the present study, a large scale model test on a vacuum consolidation method using vacuum well, permeable layer and drains, which was developed to promote early consolidation of such reclaimed ground, was analyzed using a three-dimensional soil-water coupled finite deformation analysis code that can accurately describe the large compression of unconsolidated soil. The analysis accurately reproduced the test results, and showed clearly how the negative pressure propagated efficiently and accelerated settlement due to the effect of the underlying permeable layer and vertical drain.
