Abstract
A system of prefabricated vertical drains (PVDs) combined with vacuum pressure and surcharge preloading has become an attractive ground improvement alternative in terms of both cost and effectiveness. This technique accelerates consolidation by promoting rapid radial flow, which decreases the excess pore pressure while increasing the effective stress. These recent techniques have been applied to various real life projects in Australia and Southeast Asia. Some of the new design concepts include the role of overlapping smear zones due to PVD-mandrel penetration, single drain and multi-drain analyses. These recent advances enable greater accuracy in the prediction of excess pore water pressure, and lateral and vertical displacement of the stabilised ground. This keynote paper presents an overview of the theoretical and practical developments and salient findings of soft ground improvement via PVD and vacuum preloading, with applications to selected case studies in Australia.
