Soft Ground Improvement—Theoretical, Experimental, Numerical and Field Studies
Abstract Much of the world’s essential infrastructure is built along congested coastal belts that are composed of weak, highly compressible and low permeable soils to significant depths. Soft alluvial and marine clay has very low bearing capacity and excessive settlement, properties which pose design and maintenance implications for tall structures, large commercial buildings, as well as port and transport infrastructure; these properties often hamper the development of transportation infrastructure including embankments. These very soft deposits must, therefore, be stabilised before constructing any infrastructure in order to prevent unacceptable differential settlement. Several ground improvement techniques to improve soft ground have been applied by different researches, of which Prefabricated Vertical Drains (PVDs) combined with surcharge and vacuum preloading is an efficient, cost-effective and popular technique to accelerate consolidation. This paper presents an overview of the theoretical, experimental and numerical developments of soft ground improvement via PVDs including natural fibre drains combined with surcharge and vacuum preloading, with applications to selected case studies.
