Numerical simulations for the bearing capacity of circular footings

Résumé

The aim of this paper is the computation of the failure loads of a rough rigid circular footing subjected to a vertical or inclined loading using the finite difference code FLAC3D. For the case of vertical load, controlled downward vertical velocities are applied to the footing nodes until a steady state of plastic flow is obtained in the soil. For the construction of the HV( , ) failure envelope of an inclined load, a uniform normal stress distribution is first applied to the base of the footing and the system is solved until it reaches an equilibrium state. Then, controlled horizontal velocities are applied to the nodes of the footing bottom until a steady state of plastic flow is obtained in the soil. Results of failure loads are presented and compared with those of other authors. Finally, the normal and shear contact stresses acting at the soil-footing interface are presented and discussed.
