• Abstract:
  The AASHTO codes for Load Resistance Factored Design (LRFD) regarding shallow bridge foundations ; and walls have been implemented into a set of spreadsheet algorithms to facilitate the calculations of bearing ; capacity and footing settlements on natural soils in the State of Georgia. Specifically, the approach applies ; to soils exhibiting drained behavior during loading, including clean to silty and clayey sands and granular ; soils of the Atlantic Coastal Plain and residual silty sands to sandy silts of the Appalachian Piedmont and ; Blue Ridge geologies. The methodology permits the sizing of foundations based on site-specific data input ; for a given project, using in-situ field data obtained from either: (a) standard penetration tests (SPT), (b) ; cone penetration tests (CPT), and/or (c) flat plate dilatometer tests (DMT). This report provides the ; background information concerning the equations, calculation procedures, and reference sources that are ; used. Specifically, the technical review covers the calculations of bearing capacity from limit plasticity ; theory, settlement predictions using elastic continuum solutions, and geoparameter evaluations from SPT, ; CPT, and DMT, as well as examples for each of these tests.
