Sustainability of Combined Vacuum and Surcharge Preloading
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. Satisfactory vacuum pressures can be sustaine...
متن کاملVacuum preloading for a truck parking area in Luhtaanmäki
City of Vantaa considers constructing a truck parking area and a filling station on a soft clay deposit in Luhtaanmäki, Vantaa (in Finland). The aim of this study was to evaluate whether vacuum preloading with vertical drains is a feasible ground improvement method for the site. Besides in situ –tests and classification tests, overall 18 oedometer tests were carried out. Preliminary design of v...
متن کاملAn analytical solution for two-dimensional vacuum preloading combined with electro-osmosis consolidation using EKG electrodes
China is a country with vast territory, but economic development and population growth have reduced the usable land resources in recent years. Therefore, reclamation by pumping and filling is carried out in eastern coastal regions of China in order to meet the needs of urbanization. However, large areas of reclaimed land need rapid drainage consolidation treatment. Based on past researches on h...
متن کاملCurrent state of the art in vacuum preloading for stabilising soft soil
In this paper the analytical solutions for radial consolidation that include time dependent surcharge loading and vacuum pressure are proposed, whilst also considering the impact of the parabolic variation of permeability in the smear zone. The use of the spectral method for multilayered soil consolidation is introduced and verified. The Elliptical Cavity Expansion Theory is used to predict the...
متن کاملAnalytical solution for vacuum preloading considering the nonlinear distribution of horizontal permeability within the smear zone
The vacuum preloading is an effective method which is widely used in ground treatment. In consolidation analysis, the soil around prefabricated vertical drain (PVD) is traditionally divided into smear zone and undisturbed zone, both with constant permeability. In reality, the permeability of soil changes continuously within the smear zone. In this study, the horizontal permeability coefficient ...
