In designing reinforced earth structures, apparent cohesion is often assumed to exist in the reinforced domain, by horizontally spreading geosynthetics within embankments. This assumption has been justified by Scholosser and Long (1973) who carried a series of triaxial compression tests using planner aluminum foils as the reinforcement. The authors investigate the reinforcing..effect in the triaxial compression tests performed by many researchers in the past, in which various kind of reinforcement material and testing procedure are employed. The result shows that the observed degree of reinforcement effect is considerably different from each other. The authors performed a series of triaxial compression tests using three types of reinforcement materials, each of which has a different tensile property. As the result, it was found that the apparent cohesion is clearly observed under appropriate conditions. The conditions where the apparent cohesion is generated is also clarified.
