Abstract

This study presents the results of a numerical investigation into the undrained bearing capacity of circular footings resting on two-layered homogeneous clay under V-H and V-M loading, respectively. Small displacement finite element solutions are expressed in the familiar form of failure envelopes in the loading plane. The swipe tests were employed to investigate the failure envelops in V-H and V-M loading. The results from the present analysis agree well with existing solutions. The effects of relative top layer thickness (H/D) and strength (su-t/su-b) difference between two layers are examined. The failure envelopes for both V-M and V-H loading evolve with a decrease in the strength ratio su-t/su-b. In addition, the strength ratio su-t/su-b has little effect on the failure envelopes of circular foundations for H/D =1.
