Websheet program for the design of three types of retaining walls based on AASHTO LRFD specifications were developed, which will facilitate the design of these walls for different geometry and soil properties. All analyses undertaken dealt only with the external stability of the wall, i.e., its resistance to overturning, sliding and bearing failure. how to delete clever portalWebThe design of a Geosynthetic Reinforced Soil (GRS) wall for internal stability against pullout failure requires computing the reinforcement embedment length. Therefore, the location of failure plane is an important input for this design.
