A note on failure mechanisms in soil beneath foundations
Abstract A small-element analysis is presented whereby surfaces of sliding beneath foundations may be determined. It is shown that, for a uniform cohesive soil under undrained conditions, these surfaces compare favourably with those observed in practice beneath loads that Terzaghi considered to be the ultimate bearing capacity. The minimum load to cause local shear is shown to be similar to that proposed by Terzaghi. An explanation is suggested for the observation of humping next to failed foundations without the necessary observation of a slip surface there in practice.
