A review of recent developments in soft soil improvement through consolidation is presented in this paper. The salient aspects described here range from fundamental analysis to methods of implementation. The methods and processes covered here include vertical drains; vacuum preloading or combined vacuum and fill surcharge; and dynamic consolidation with enhanced drainage or vacuum. Discussions on methods to evaluate the degree of consolidation using field data are also made, including various limitations and comparison between the processes where warranted. New types of prefabricated vertical drains (PVD) and new applications such as thermal or electric PVDs are also introduced. Keywords: Consolidation, Soft soil, Soil improvement, Vertical drains, Vacuum preloading.
