DISTRIBUTIONS OF LATERAL EARTH PRESSURE AND REINFORCEMENT TENSION INSIDE THE GEOSYNTHETIC REINFORCED SOIL RETAINING WALLS

Present internal stability design of the geosynthetic reinforced soil (GSL) walls is based on the limiting equilibrium concepts and requires an assumption of the lateral earth pressure distribution against the face of the reinforced section in order to obtain the tensile stresses resisted by the reinforcement. Available evidence from full-scale and model GRS walls indicates that these assumptions tend to significantly overestimate the internal stress distribution within the structure. In an effort to develop an appropriate internal stability design for GRS walls, an alternate approach to obtain the distribution of lateral earth pressure behind the wall face is presented in this paper. It also appears to improve estimates of the lateral earth pressure distribution behind the wall face and reinforcement tensions of GRS walls.
