Finite element solutions for some bearing capacity problems

The finite element method provides an attractive method to analyse many limit problems in geomechanics where mathematical solutions are not possible. Bearing capacity analysis is one such problem that has practical significance. Finite element methods are increasingly being used for the analysis of footings to predict both the ultimate capacities and also to predict the expected deformations. Although, finite element method is a versatile tool, the results from these analyses are very much influenced by the procedures used. The results are influenced by the type of element used, size of mesh, solution techniques used, order of integration, etc. This paper will discuss the influence of these aspects on the results from the finite element analyses. Several classes of bearing capacity problems have been considered in this investigation. The finite element techniques are applied in this paper to study the behaviour of interacting footing and stone columns.
