Upper Bound Solutions for Bearing Capacity of Footings on Anisotropic Cohesive Soils
A closed form solution for the undrained bearing capacity of strip footings on anisotropic cohesive soils using kinematic approach of limit analysis has been presented in this article. A translational failure mechanism with variable wedge angles is attempted and the resulting upper bound was analytically determined leading to an analytical expression for the bearing capacity factor. The influence of degree of soil anisotropy on the corresponding value for the bearing capacity factor was evaluated and the results are compared with available pertinent solution. An advantage of the closed-form solution is that it is more convenient for complex computations as well as it clearly depicts the effect of soil anisotropy on the bearing capacity as opposed to tabular or graphical representations where such an effect is obstructed in a number of charts and/or tables.
