BEARING CAPACITY OF SKIRTED CIRCULAR FOOTINGS ON SAND

Abstract

This thesis presents the analysis results of bearing capacity of skirted circular footings on sand. In fact this skirt provides the soil confinement. In this way I studied the influence of soil confinement which is provided by using a skirt of different height and diameter combination. Initially, the response of non confined case was determined and then compared with that of confined soil, with different combination of height and diameter of the skirt. The results indicates that the bearing capacity of circular footing can be appreciably increased by soil confinement. It was concluded that such reinforcement resists lateral displacement of soil underneath the footing, leading to a significant improvement in the response of the footing. The analysis results give the clear indication that when we are increasing thediameter of the skirt, the bearing capacity is increased up to a certain limit of diameter. After increasing the diameter of the skirt above this optimize limit the...
