ABSTRACT
EFFECT OF SIZE OF FOOTINGS ON SETTLEMENT Figure 13.3a gives typical load-settlement relationships for footings of different widths on the surface of a homogeneous sand deposit. It can be seen that the ultimate bearing capacities of the footings per unit area increase with the increase in the widths of the footings. However, for a given settlement 8, such as 25 mm, the soil pressure is greater for a footing of intermediate width Bb than for a large footing with Bc. The pressures corresponding to the three widths intermediate, large and narrow, are indicated by points b, c and a respectively.
