13. Soil Properties and Foundation: Note that cohesion of the reinforced or retained cannot be considered in AASHTO or NCMA. To assess bearing capacity, the foundation properties are input using this dialog. Note that while in slope stability the actual soil profile is specified, in bearing capacity the foundation soil is idealized as uniform (i.e., to be used by Meyerhof bearing capacity for eccentric load method). The user may select presumptive bearing pressures thus skip the traditional calculations if deemed to be overly conservative for a base of flexible wall which is treated as footing. However, this option is beyond AASHTO guidelines.
