Behaviour of ring footing over reinforced sand

Abstract

The main objective of my study is to investigate the use of geo-synthetics in geotechnical characteristics of sand and to evaluate the effects of geo-synthetics on shear strength of sand by carrying out direct shear tests and to evaluate the increase in the bearing capacity of sand by the application of footing load tests over sand at different relative densities. The experiments performed to evaluate the change in bearing capacity of sand after reinforcement show that there is an increase in bearing capacity of sand on reinforcement .This increase in bearing capacity increases with reinforcement provided upto a depth of B from the top layer of sand and then the increase gradually reduces at a depth of 1.5B and 2B from the top layer of the sand.
