Design Method for Cover Soil Stability of Lined Multi-slope/berm Systems using Continuous Geogrid Reinforcement
This paper has analysed the stability of cover soils placed on smooth inclined multislopes sections in which the soil layer is hold by an unique and continuous geogrid reinforcement. This configuration allows to avoid the realization of anchor trenches at every berm and to interrupt the geogrid continuity. The change of direction in every vertex is considered in the transmission of tensile forces in order to represent the actual situation. Future investigation by means of trials are necessary to understand better the uplift effect in concave corners in order to get ready the analytical model.
