Analysis of Consolidation by Vertical Drain with Vacuum Preloading Based on Axisymmetric Biot’s Consolidation Theory

An 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...

Effects of partially penetrating prefabricated vertical drains and loading patterns on vacuum consolidation

In this study, numerical modeling of a multi-drain system is employed to determine the optimum penetration depth of prefabricated vertical drains (PVDs) and the vacuum pressure that provides the maximum consolidation settlement and less lateral displacements. The plane strain analysis using an equivalent permeability with transformed unit cell geometry was considered for varying drain length an...

Analytical solutions and design curves for vacuum-assisted consolidation with both vertical and horizontal drainage

Settlements and Consolidation Rates under Embankments in a Soft Soil with Vertical Drains

In this paper, a study was carried out in order to estimate settlements and consolidation rates under embankments constructed on Moroccan soft soils.  Settlement measurements in several embankments in High Speed Railway project between two Moroccan cities, Tangier and Assilah,  were analyzed. The objective of this study is to estimate settlement values and settlement rates, with sufficient prec...

Analysis of soil consolidation by vertical drains with double porosity model

The soil around a drain well is traditionally divided into smeared zone and undisturbed zone with constant hydraulic conductivity. In reality, hydraulic conductivity of the soil changes continuously and it may not be always appropriate to approximate its distribution with two zones. In this study, the horizontal hydraulic conductivity of the soil is described by an arbitrary function of radial ...
