Undrained bearing capacity factors for ring footings in heterogeneous soil
Abstract This paper examines the undrained vertical bearing capacity of a ring rough footing embedded in heterogeneous soil. Stability solutions for a wide range of geometric and material combinations are obtained by small-strain finite element analysis. Design tables and charts are provided for evaluating undrained bearing capacity factors as a function of the dimensionless parameters related to footing internal opening, embedment and soil strength heterogeneity. The results from the present analysis are compared with the experimental data and existing solutions reported in the literature. The transition from shallow to deep failure modes for the ring footing is broadly discussed in terms of the displacement pattern. The undrained bearing capacity factors for different values of soil friction angle are also studied to investigate the effect of friction angle on the undrained stability of ring footings in heterogeneous soil.
