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.
