Abstract:

Four full size footings were load tested at a site in Texas. The embedded footings were situated on a thin layer of stiff clay underlain by a thick deposit of medium dense to dense sand. A comprehensive in situ and laboratory testing program was performed to evaluate the engineering properties of the subsoils. Finite element analysis was performed to evaluate the effect of embedment and subsoil layering. The load/settlement response of the footings was compared with 20 procedures for predicting bearing pressure at a settlement of 25 mm (1 in.).
