Abstract

This paper examines the undrained bearing capacity of shallow circular foundations on structured soil deposits. Guidelines are given to identify the importance of structural features of the soil when assesing its bearing resistance. Results obtained using a finite element model have been compared with those from existing bearing capacity formulae based largely on plasticity theory. A new bearing capacity equation has been proposed incorporating critical state soil parameters and additional parameters that quantify the effects of soil structure on its mechanical behaviour.
