Abstract
Embankment construction on marginal soft ground has increased considerably over recent years due to increase in infrastructure development activities. The low bearing capacity and excessive settlement characteristics of soft ground can make this a very difficult task. Although consolidation based ground improvement techniques can be used to overcome this problem, they are time consuming and not suitable for fast tract construction schemes. Geosynthetic reinforced pile-supported (GRPS) embankments is one solution for embankment construction over soft ground and an attractive construction technology for fast track embankment construction schemes. The overall performance of GRPS embankment can vary with different parameters such as pile spacing, pile diameter, elastic modulus of the piles and the stiffness of the geosythetic layer. Therefore having an understanding about the effect of these factors on the performance of GRPS embankments can be extremely beneficial for practitioners both in the design and construction stages. This paper presents a finite element parametric study carried out on a GRPS embankment in order to assess the embankment behaviour with the variation of above parameters.
