Field Studies of an Instrumented Model Pile in Clay
An instrumented model pile was used to investigate the fundamental behavior of driven cylindrical steel piles, in clay soils. Data are described from two test-bed sites, one with heavily overconsolidated clay, and one with normally consolidated. These confirm that a residual shear surface is formed adjacent to the pile shaft during installation. Comparisons with other site investigation data and cavity expansion theoretical predictions suggest that stress relief immediately behind the pile tip during installation gives rise to total radial stress and pore pressure measurements on the shaft which are lower than this simple model predicts. However, the data did indicate that the radial effective stress might be successfully predicted.
