A THEORETICAL STUDY OF PILE HEAVE

Installation of a driven pile displaces the soil vertically and radially. The ensuing vertical soil movement causes the uplift or heave of piles already installed in the vicinity. The paper describes a theoretical study of the vertical soil movement and the pile heave due to the installation of a driven pile in clay. The clay deposit is idealized as a homogeneous isotropic incompressbile linear elastic half-space. Pile installation is stimulated by the injection of material along the pile axis with a constant intensity. The resulting soil movement is obtained using the source-sink imaging technique. The heave of a pile already installed is obtained from the interaction between the pile and the vertical soil movement. Numerical results are presented showing how the soil movement is affected by the dimensions of the penetrating pile. The pile heave is affected by the ratio of the Young's moduli of the pile and soil, in addition to the pile dimensions and pile spacing. A number of reported case histories are analyzed; in general, the theoretical and observed behavior show an encouraging measure of agreement.
