This paper is results of numerical works of investigating effects of horizontal drain arrangements on vacuum consolidation. Extensive numerical analyses were carried out to find the appropriate arrangements of horizontal drain of vacuum consolidation. Commercially available program of CRISP, well known to be good to modelling the behavior of clay material, was used. Cam-clay model, based on the Critical State of Soil Mechanics(CSSM), was used to simulate the geotechnical engineering behavior of clay. Model test results carried out previously in the laboratory were compared with numerically estimated results and it was found that results about consolidational settlement with times were in good agreements. Based on this confirmation, parametric numerical study was performed to investigate effects of horizontal drain arrangements on vacuum consolidation with changing the vertical and horizontal spacings between drains for the given soil properties and vacuum. The effect of distance of drain located in top layer from the surface of the ground on the settlement due to vacuum was also investigated. As a results of numerical analyses, appropriate arrangements of horizontal drain to maximize the consolidation settlement due to vacuum were found. The mechanism of vacuum consolidation about the vacuum pressures being transferred to the effective stresses around drains was also evaluated.

This paper is experimental results of investigating the efficiency of horizontal vacuum drainage system. Effects of size and shape of drain on horizontal vacuum drainage were studied. Model tests in the laboratory with soft marine clay were carried out with drain pipe of having three different diameters and PBD (Plastic Board Drain) of strip shape so that consolidation settlement of soft clay due to applied vacuum pressure, amount of discharge, ground settlement and distributions of pore pressure and undrained shear strength were measured during testing. From results of model test, amount of discharge due to vacuum pressure was increased with the diameter of pipe drain whereas the drain efficiency of pipe in per unit area of drain surface was decreased with diameter of pipe. The rate of discharge per unit time was reduced very fast with diameter of pipe. Settlement of ground surface with time was increased with diameter of pipe as a result of increase of discharge to drain pipe.

Nonlinear Consolidation Analysis of Reclaimed Ground with Lateral Drain Vacuum Consolidation
Kyu Hwan Lee,Myung Chan Kang,Dae Suck Jung 대한토목학회 2006 KSCE journal of civil engineering Vol.10 No.6
Vacuum consolidation is a soil improvement technique that accelerates consolidation of soft ground by using the action of the atmospheric pressure in combination with a ground pore-pressure relief system. Dredged and reclaimed soft clays form slurry state which is very high water content and very low shear strength, experience large self-weight consolidation with nonlinear compressibility and permeability phenomenon. Applying vacuum consolidation method with horizontal drain in order to improve reclaimed soft ground, non-linear finite consolidation phenomenon takes place. To analyze the non-linear finite consolidation of reclaimed ground, a material functions which represent nonlinear effective stress-void ratio-permeability relationship were obtained with slurry consolidation apparatus and numerical analysis program was developed. From the back analysis of pilot test, a material functions which fit to field condition were obtained. It shows reasonably good match to the observed settlement. Design parameter's effects with lateral vacuum method were analyzed.
