Abstract

In the present paper, a statistical limit analysis was carried out to estimate the bearing capacity of the surface strip and the circular base resting on dense sand under the loose sand layer. The analysis was accompanied by a lower and upper bound limit analysis in combination with finite elements and second-order conic programming (SOCP). In this approach, the Mohr–Coulomb yield criterion was used to model soil behavior. Assuming an associated flow rule, rigorous lower and upper bounds on ultimate bearing capacity are obtained with the use of this technique. Comparisons were made with the available solutions from the literature wherever applicable.
