The baseline solution defines the required reinforcement/connection load at any relevant location so as to produce a user-prescribed limit state. This baseline solution provides a rational basis for selecting geosynthetic and facing considering long-term strengths values. New Features for assessing Internal Stability – The Baseline Solution: It also can be used for assessing the stability of unreinforced slopes.For a given problem (i.e., tiered slope/wall, different soil layers, complex layout of reinforcement, facing units, surcharge loadings, pullout interaction parameters, seismicity, seeping water, and user-specified rear-end reinforcement resistance) and a given target factor of safety, ReSSA+ calculates the maximum tensile resistance in the reinforcement, Tmax, its location, and the connection load, To, for each layer. Users of MSEW (3.0) and/or ReSSA (3.0) are advised to upgrade to MSEW+ and/or ReSSA+. 2 Thus the crack in the top lamina is described by: x 0, < x < +a, and h < 2 12x < h +h The crack surface is assumed to be 3- 2 3 traction free. Support is no longer available for MSEW (3.0) or ReSSA (3.0). Program ReSSA+ is an interactive, graphically rich program, allowing the designer to analyze reinforced walls and slopes including embankments with basal reinforcement.
