Abstract
For design and construction of any infrastructure in-situ geotechnical tests are must and provide vital information and data. There are various insitu-tests for estimation of engineering properties of soil and its bearing capacity. The Standard Penetration Test (SPT) is one of the oldest and most commonly used insitu tests worldwide. In India normally any soil investigation and boring programme is not considered complete without SPT. Various researchers have suggested various correlations to estimate safe bearing capacity or allowable soil pressure for shallow foundations on the basis of SPT values. This paper presents the brief review of such commonly used correlations and proposes a new correlation to estimate allowable soil pressure for isolated footings.
