Question

Quizplus · Accepted Answer

The correct formula for the depth of foundation D is D = 0.00775 a?P. This formula is derived from the theory of soil mechanics and takes into account the upward pressure on the slab, the projection of the slab on either side of the wall, and the allowable bearing capacity of the soil.
