Abstract
In order to clarify bearing capacity of a structure-sand ground system subjected to various types of loading, a series of model tests were carried out under several static and cyclic loading conditions. It was found that; (1) lateral flow behavior of the ground depends strongly on the settlement performance of a structure, (2) bearing capacity of the ground can be evaluated by a failure envelope which is depicted in M-V-H plane irrespective of the difference in loading conditions, and (3) stability of the sand ground-structure system may be evalutated by using the parameter Vδ/Vρ which is adopted as the measure of lateral deformation volume in this study.
