Abstract
Construction on soft foundation soils can be a challenging task for the geotechnical engineers due to the undesirable characteristics of soft soil such as high compressibility, insufficient shear strength and low bearing capacity. Embankments constructed on such grounds will be subjected to considerable absolute or differential settlements. These settlements have to be limited to permissible values in order to maintain the stability and durability of the structures concerned. Among various ground improvement methods used to overcome these difficulties, geosynthetic reinforced pile-supported (GRPS) embankments are considered to be a reliable solution. Various researchers have introduced different methods to design GRPS embankments using different load transfer mechanisms. This paper presents a three-dimensional numerical study using the finite element method conducted on GRPS embankments in order to compare some currently available design methods with three dimensional model results. Based on these model results, the inconsistencies in currently available design models are discussed in detail.
