Comparisons of Probe and Pile Tests
A large body of experimental data has been collected on pile-soil setup and axial load-deformation behavior in highly plastic clays near the Mississippi River delta. The data provide unique insight into the behavior of foundation piles subjected to static and cyclic axial loading in both tension and compression. Static tests with a 30-inch-diameter pile driven to a penetration of 234 ft below the mudline are compared with instrumented pile segment probes 1.72 and 3.0 inches in diameter. Excellent agreement is shown between the pile and the probes. Correlations include (a) the effects of diameter and wall thickness on the rate of consolidation and setup, (b) the effects of time and the degree of consolidation on the static axial capacity, and (c) the effects of depth and loading history on the nonlinear shear transfer versus displacement. In this paper, correlations are developed relating the ultimate static shear transfer to commonly measured soil properties, including directly relating the shear transfer to the undrained shear strength. It is shown that complex effective stress methods are not necessary for normally consolidated and underconsolidated highly plastic clay soils.
