Installation of prefabricated vertical drains using a mandrel causes disturbance of clay
surrounding the drain, resulting in a" smear" zone of reduced permeability. In this paper, an …

A vertical drain radial consolidation equation based on a parabolic reduction in permeability
toward the drain is presented. The proposed equation, based on Hansbo's equal strain …

Improvement of soft ground by preloading with prefabricated vertical drains (PVDs) is a
common practice in the field of ground engineering. PVDs accelerate the consolidation …

Vertical drains increase the rate of consolidation in soft soils by facilitating faster dissipation
of excess pore water pressure through short, horizontal drainage paths. This paper presents …

A novel use of the spectral method to determine excess pore water pressure during vertical
consolidation of multi-layered soil with time constant material properties is presented …

Various analytical solutions have been proposed for a unit-cell consolidation with a vertical
drain under surcharge loading. These solutions involve different assumptions to address …

Natural prefabricated vertical drains (NPVDs) produced from biodegradable materials such
as jute and coir have some distinct advantages over conventional polymeric prefabricated …

Vertical drains are extensively used along with the preloading technique as an effective
ground improvement method for soft compressible soils. The installation of prefabricated …

Dans cette étude, on a fait le montage d'un modèle physique avec instrumentation complète
qui a été utilisé pour mesurer le processus de pleine consolidation d'un cylindre d'argile …

A new method, the η or 'eta'method, for modeling consolidation by vertical and horizontal
drains is presented. The approach is applicable in one, two and three dimensional as well …
