Influence of Footing Embedment on the Scale Effect of Footings

The bearing capacity tests were conducted in a centrifuge to examine the influence of the footing embedment on the scale effect of the footings.Test results showed that the scale effect became more significant with the increasing of footing embedment.Not only the bearing capacity factor Nγ decreased as the footing size increased,but also the bearing capacity factor Nq decreased as the footing size increased.Namely there also existed a scale effect for the bearing capacity Nq.Furthermore,Nq decreased more sharply as the footing embedment increased.
