THE BEARING CAPACITY OF CLAYS

The results of theoretical and experimental studies of the properties of clay soils lead to a very simple equation for computing the ultimate bearing capacity or maximum pressure to which the soil can be subjected without complete failure. This equation refers to a rectangular footing having a width B and length L. The expression is Q(sub d) equals 2.85 Q(sub u) (1 plus 0.3 B/L) in which Q(sub u) is the unconfined compressive strength of the clay beneath the loaded area, and Q(sub d) is the ultimate bearing capacity. The unconfined compressive strength of a clay soil can be determined readily by relatively rapid and inexpensive methods.
