Abstract: The large-scale triaxial consolidation drained shear tests have been carried out for geobelt reinforced crushed gravel soil and non-reinforced crushed gravel soil. The effects of reinforcement on stress-strain and shear strength of gravel soil are studied. The experimental results show that the failure strength and strain of the reinforced soil are increased. It is seen that the curves of strength between reinforced and non-reinforced soil are almost completely parallel; and their friction angles are fairly same; cohesion of reinforced soil is higher than the non-reinforced soil by the strength envelopes of reinforced and non-reinforced soil. The properties of shear strength of geobelt reinforced crushed gravel soil are studied by analyzing the relationship of stress-strain of reinforced crushed gravel soil. A calculation formula of shear strength of geobelt reinforced crushed gravel soil is drawn. This paper provides an experiment basis for studying mechanism of geobelt reinforced crushed gravel soil further.

Key words: geobelt, reinforced crushed gravel soil, triaxial test, stress-strain, shear strength
