Abstract

In this paper, an experimental study is presented under various stress paths for unreinforced and reinforced soil. Drained triaxial tests were conducted using a computer controlled GDS triaxial apparatus. Test results show that non-woven geotextile reinforced soils exhibit higher failure strains and volume contraction than unreinforced soils. Failure strains and the strength increase with increase in number of layers. A simplified approach for numerical calculations were proposed to predict the shear strength and the coefficient of interface friction of reinforced soils for conventional triaxial compression (CTC) stress paths. Charts were also presented to predict the strength of reinforced soil and to determine the coefficient of the interface friction from test results and predictions are satisfactory.
