Abstract
![CDATA[This paper presents a parametric study for Geosynthetic Reinforced Column Supported (GRCS) embankments considering the full three-dimensional geometry. Influencing factors considered in the paramet-ric study are: (i) elastic modulus, spacing and diameter of Deep Cement Mixed (DCM) columns, (ii) elastic modulus and permeability of soft foundation soil, (iii) tensile stiffness of geosynthetic, (iv) thickness of the platform layer, (v) embankment height and (vi) friction angle of the embankment fill material. Only the most important parameters governing the embankment behaviour are presented in this paper, which include (i) total and differential settlements, (ii) tension developed in the geosynthetic, (iii) lateral deformation of columns, (iv) efficiency coefficient of columns and (v) arching ratio. Based on the results of the parametric study, it was found that the most important design parameters to be considered in GRCS embankment design procedures are column spacing, elastic modulus of soft soil and embankment height followed by column diameter.]]
