Abstract
Nowadays, the application of a variety of novel reinforcing elements for the design and implementation processes of reinforced soil systems is proliferating. Obviously, it is deserving of note that the selection of the reinforcing element type is of bountiful importance in ameliorating the performance of reinforced soil walls. More latterly, a new type of reinforcing elements labeled grid-anchors conjoining anchors, made up of polymeric substances, with conventional geogrid has been invented, which can generate specific capabilities in reinforced soil walls. In this research, the effect of using grid-anchors on the bearing capacity of strip foundations and lateral deformations of the reinforced soil wall surface in a small-scale laboratory case are investigated. On this purpose, the bearing capacity of a strip foundation resting on a reinforced soil wall and lateral deformations of the wall in unreinforced, geogrid-reinforced and anchor-grid reinforced conditions at differential spaces of the foundation from the wall edge are scrutinized and compared. The results of the experiments disclosed that using anchor-grids in the reinforcement of the reinforced soil wall has resulted in increment of the bearing capacity of the strip foundation locating on the upward parcel of the wall up to 5.5 and 1.5 times in relation to the unreinforced and geogrid-reinforced conditions, respectively. Additionally, anchor-grids can dwindle later wall deformations up to 66% and 16% compared with the unreinforced and geogrid-reinforced conditions, respectively.
