ABSTRACT
The present analysis is limited to a system of two distinct soil layers. For a footing located in the upper layer at a depth Df below the ground level, the failure surfaces at ultimate load may either lie completely in the upper layer or may cross the boundary of the two layers. Further, we may come across the upper layer strong and the lower layer weak or vice versa. In either case, a general analysis for (e -l/J) will be presented and will show the same analysis holds true if the soil layers are anyone of the categories belonging to sand or clay.
