Sustainability of Combined Vacuum and Surcharge Preloading [PDF]
Geo-Congress 2014 Technical Papers, 2014 This paper presents a review of combined vacuum consolidation and surcharge preloading which is arguably more sustainable approach to soft-soil ground improvement than other strategies in reducing post-construction settlements. Vacuum consolidation has become more prevalent with technological developments in vertical drains, pumps and geosynthetics ...

The effect of initial water content on the consolidation of dredged slurry under vacuum preloading
Rock and Soil Mechanics, 2021 In the process of treating the dredged slurry under vacuum preloading combined with the prefabricated vertical drains (PVDs), a dense “soil column” with low permeability will be formed around the PVD, which results in a poor drainage condition and an ...
