INITIAL RESPONSE OF FOUNDATIONS ON MIXED STRATIGRAPHIES

A procedure for easily computing the initial settlement of shallow foundations on mixed stratigraphies has been developed. Applicable soil conditions are primarily stiff to hard clays with horizontal layers of dense to very dense sand. The Revised Gibson Model makes use of a simple equation for elastic settlement of axisymmetric footings. An equivalent modulus that accounts for the variations in soil modulus with depth beneath the footing is one of the primary input parameters to the equation. The effect of a sand layer within the foundation soils on initial settlements is included in the procedure by means of an additional factor obtained from parametric charts. Twelve case histories, including elevated and ground storage tanks and multistory buildings, are used to evaluate the effectiveness of the new initial settlement computational method.
