Abstract

 A finite element program based on elastic - perfect plastic soil model of Mohr- Coulomb criteria was used to study the effect of load inclination and load eccentricity on the bearing capacity coefficients of surface footing. The existing formulae for iγ, ic, ieγ and iec have also been reviewed for the sake of comparison, and the shape and the size of rupture zones have been discussed. The results obtained from the present computations were compared to the available experimental results and others proposed relationships. The results showed that there are many factors which influence the computational results so that it is not that easy to judge clearly at this stage. Some distinct and general conclusions could, however, be made as follows : 1) Application of a suitable finite element program based on the elastic - perfect plastic soil model with Mohr - Coulomb criteria is able to illustrate the the effects of influential factors in determining the soil bearing capacity . 2) The factors of inclination and eccentricity are dependent on the friction angle of the soil, so as for large values ofφ ,the descending rate of these factors becomes more distinguished . This effect has not been included in the previous formulae.3) The effect of dilatancy angle can basically change the descending rate of the mentioned factors .This effect has not been considered in the previous literature. 4) The shapes of the rupture zones are similar to the experimentally observed shapes, but their sizes obtained from the present study are smaller than those have been measured in the tests with the same conditions.
