Question

A footing 33m is to be located at a depth of 1.5m in a sand deposit, the water table being 3.5m below the surface. Values of standard penetration resistance were determined as detailed in Table 8.5. Determine the allowable bearing capacity using the various design methods A footing 33m is to be located at a depth of 1.5m in a sand deposit, the water table being 3.5m below the surface.

Explanation / Answer

Then the allowable bearing capacity for a settlement of 25mm at the end of construction

is given by

qa ¼ si

B0:7Ic

¼ 25

30:7 0:068

¼ 170kN=m2

In design the usual requirement is to determine the foundation dimensions for the

support of a given load and an iterative technique is necessary.
