Strength and Deformational Properties of Geocapsule-Reinforced Sand

Abstract

Geocapsule which envelops cohesionless granular materials by geosynthetics may develop an apparent cohesion component as well as its frictional resistance. In this study, the strength and deformational properties of geocapsule-reinforced dry fine sands were invesitigated in an uniaxial compression test.
The experimental results showed that the increase in the uniaxial compressive strength and by decreases in the failure strain. The apparent cohesion of geocapsule-reinforced sand can be estimated using the shear box test data of the sand.It was found that stress-strain relationships of geocapsulated soil sample were affected by the volume of the specimen.
