A Study on Shear strength and Friction Properties of Fiber-Mixed Soil as Backfill Material in Reinforced Earth Wall
섬유혼합 보강토의 전단강도특성 및 마찰특성 연구
Abstract
A series of experimental study are performed to evaluate the shear strength and friction properties of fiber-mixed soil as backfill material in reinforced earth wall. In order to evaluate the properties of shear strength the big-size direct shear tests are carried out and on the friction properties, the shear friction tests and the pull-out tests are performed. In the results, when the mixed ratio of the net type fiber is 0.2%, the reinforcement effect was better than the others. Also the reinforcement effect of the net type fiber was larger than that of the line type fiber.
