The Theory of Penetration Failure in Compact Soils
Abstract
A unified procedure is employed in the determination of the penetration resistance of continuous strip footings and foundations buried up to ten times their width in compact soil. The quasi-static analysis is based on the soil failure theory of classical soil mechanics. The theoretical data is presented by means of a two part additive equation, two dimensionless factors describing the effect of weight and cohesion. These factors are functions not only of the angle of internal friction and the penetration ratio but also of the shaft parameters and the dimensionless group dependent on the density, the cohesion and the breadth of the footing. Experimental verification is given both of the penetration resistance and of the failure geometry by model testing in a glass sided soil tank. The penetration resistance data in compact soil support the quantitative theoretical values. The measured failure patterns are shown to be in agreement with the predicted shapes only when the effect of changing soil properties and constraints are carefully evaluated throughout the duration of the test.
