Experimental Study on Footings in Layered Soil
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.
On the basis of topographic relationships between the emerged and submerged parts of coasts and between littoral and continental platform profiles, a classification scheme is proposed for coasts in which five principal morphologic types are distinguished. Examples of the different types are given.
