Modeling and analysis of reclamation process

Abstract The process of reclamation consists of laying a geotextile and spreading granular fill over it in several lifts, each lift being densified before the next one is spread. Self-weight of the granular fill increases with increasing height of each lift causing the ground to settle, with the fill placed during the previous lifts acting as a shear layer. The clay, granular fill and the reinforcement layers are modeled by non-linear Winkler springs, Pasternak shear layer of increasing stiffness and rough membrane respectively incorporating hyperbolic (Kondner, 1963) responses for stress - displacement relation of soft clay and shear stress - shear strain relation for the granular fill. As the reclamation process entails large settlements, finite deformation theory is used in the present work. The steps involved in modeling of the reclamation process are described herein.
