Strength of Sand Reinforced with Full Scale Reinforcement Material in Large Scale Triaxial Compression Test

Abstract

A reinforcing mechanism, and strength and deformation characteristics of the reinforced soil have been investigated by a laboratory element test using a small size specimen. However, the properties of soil that reinforced with a full scall reinforcing material can not be studied by the laboratory test as the size of specimen is very small.
In this paper, a series of large scale triaxial compression tests were performed in order to investigate the strength and deformation characteristics of sand that reinforced with full scall reinforcing materials (geo-grid, non-woven and metal strip for terre armee). The tests were carried out on a dry sand sample, the results were represented by comparing the stress-strain relation of reinforced sand with that of unreinforced sand.
