PVD improvement of soft Bangkok clay with and without vacuum preloading using analytical and numerical analyses

摘要

This paper presents the performance of improved soft Bangkok clay with prefabricated vertical drains (PVDs) combined with embankment preloading (conventional PVD method) and vacuum preloading (vacuum PVD method). The performance was evaluated in terms of settlements and flow parameters using analytical methods and numerical simulations in the ABAQUS software. The horizontal coefficient of consolidation (C-h), the ratio (k(h)/k(s)) between the horizontal hydraulic conductivity in the undisturbed
