Abstract:

Based on non-full horizontal-vertical (H-V) reinforced clay, a series of consolidated undrained triaxial tests are carried out to investigate the strength and deformation properties of clay reinforced with H-V inclusions, in which the galvanized iron sheet and plexiglass are used as reinforcing materials. The behaviour of clay reinforced with different vertical reinforcements is studied in terms of stress-strain relationship, strength property and failure mode. The influences of vertical reinforcement, confining pressure and reinforcing materials on the strength of reinforced clay are discussed. The results show that the peak deviator stress and shear strength increase greatly for clay reinforced H-V reinforcing elements as compared to unreinforced clay and clay reinforced with conventional horizontal inclusions.

Key words: horizontal-vertical (H-V) reinforcement, clay, triaxial test, strength, deformation
