Mandal Received: 21 December 2006 / Accepted: 6 July 2007 / Published online: 31 July 2007 Springer Science+Business Media B.V. 2007 Abstract Several experiments are carried out to Friction angle u () understand the deformation behavior of reinforced Geogrid GG soil retaining wall with limited fill zones under Internal friction angle of sand uss () vertical surcharge strip loading. Test set-up along Length of anchor L (m) with all the instrumentations is developed to carry out Linear variable displacement LVDT the experiments. Panel displacements and strain transducers distribution along geogrid layers are observed. Effec- Maximum dry unit weight c 3 dmax (kN/m ) tiveness of the reinforced soil wall is also evaluated Mean particle size D50 (mm) using a geogrid material. Finite element analysis is Minimum dry unit weight c 3 dmin (kN/m ) carried out using commercial software PLAXIS Normal stiffness EA (kN) version 8 for the above problem without and with Permeability in horizontal direction kx (m/day) anchoring of reinforced soil retaining wall in the Permeability in vertical direction ky (m/day) limited fill zone.
