DEPLOYABLE GEOCELL REINFORCEMENT FOR ROAD RESTORATION AND LABORATORY TESTING OF REINFORCING EFFECTS

Abstract

 Advanced soil reinforcement should be useful to carry out road restoration following a disaster. A deployable geocell reinforcement inspired by the self-deployable structure in space and mechanical engineering was designed for the road restoration. The deployment conditions and reinforcement shape were simulated. A series of laboratory tests were conducted to investigate the reinforcing effect, and it was confirmed that the soil-geocell interface shear resistance increases as the cell reinforcement confines the soil dilatancy. Based on the Taylor-Bishop energy correction formula, an empirical formula is proposed for the soil-geocell interface shear resistance.
