| Abstract: | Based on three dimensional failure mode of saturated soil mass, the further research about limit bearing capacity has been performed in this paper, and the influence of the footing shape on the limit bearing capacity has been studied. By introducing reasonable value of energy safety factor, the designing value of bearing capacity of saturated soil mass under three dimensional stability conditions has been discussed. |
