Title: Geosynthetic-reinforced and jet grout column-supported embankments on soft soils: numerical analysis and parametric study
Issue Date: 2011
Abstract: Using a computer code based on the finite element method, a study is conducted to analyse the timedependentbehaviour of a geosynthetic-reinforced and jet grout column-supported embankment on softsoils, as well as the influence of three factors: the embankment height, the elastic modulus of column andthe column spacing. The cylindrical unit cell formulation is used. The numerical model incorporates theBiot consolidation theory with soil constitutive relations simulated by the pqh critical state model. Specialemphasis is given to the analysis of several parameters: settlement, excess pore pressure, effectivestress, stress level, tension in the geosynthetic, soil arching effect and overall efficiency coefficient. 2011 Elsevier Ltd.
