Ring Footing

A ring footing is found to be of practical importance in supporting symmetrical constructions for example silos, oil storage container etc. In the present paper, numerical analysis was carried out with explicit code FLAC3D 7.0 to investigate bearing capacity of a ring footing on geogrid reinforced sand. Effects of the ratio n of its inner/outer diameter (Di/D) of a ring footing, an optimum depth to lay the geogrid layer were examined. It was found that an intersection zone was developed in soil under inner-side (aisle) of ring footing, contributing to its bearing capacity. Substantial increase of bearing capacities could be realized if ratio n of a ring footing was around 0.6. Numerical results also showed that, bearing capacity of a ring footing could increase significantly if a single-layer geogrid was laid at a proper depth under the footing. Similar contribution was found if a double-layer geogrid was implemented. However, such increases appeared to be rather limited if a triple-layer geogrid or a four-layer geogrid was used. A double-layer geogrid was recommended to increase the bearing capacity of a ring footing; the depth to lay this double-layer geogrid was also discussed.

The bearing capacity of shallow foundation near slope has always been one of the subjects of major interest in geotechnical engineering for researchers and practical engineers. This study focuses on the numerical analysis of the undrained bearing capacity for a strip footing near a slope, and subjected to a centered vertical load, using the explicit finite difference code FLAC (Fast Lagrangian Analysis of Continua). Theoretical and experimental studies confirm that, when a strip footing is near a slope, the bearing capacity must be assessed using reduction coefficients. In this study, several geometrical and mechanical parameters have been considered in order to evaluate the effect of the slope on the undrained bearing capacity. The numerical values have been compared with those available in the literature. The results show the influence on the undrained bearing capacity of the location of the footing with respect to the slope.
