The results are presented of an experimental study on strip and circular footings on a two-layered soil. The values of the ultimate bearing capacity obtained by the model tests are compared with those calculated according to the empirical method published recently by Satyanarayana and Garg, 1980. The extensive comparisons between the observed ultimate bearing capacity values and those predicted by the method reveal discrepancies ranging from 70 to 85 percent. Thus, the method needs more refinement and further experimental, and possibly field verifications before it can be recommended for practical applications.
