Theoretical Study of the Cyclic Shakedown of Laterally Loaded Piles
The paper describes a method for examining the theoretical response of single vertical piles to cyclic lateral load. The soil-pile interaction model is bilinear-elastoplastic and is based on subgrade reaction theory. The model allows the effects of soil yielding and pile-soil separation to be considered for any arbitrary loading programme. Pile displacements and bending moments can be determined at any stage during loading. By varying the tension and compression spring characteristics, several soil rheological models can be examined. Material degradation is not considered in the present analysis, and the soil properties are assumed to remain constant during cyclic loading. Attention is focussed instead on the mechanical degradation of the soil-pile system caused by plastic deformation of the soil. The increase in pile displacement during cyclic loading, resulting from the development of residual pressures along the pile or separation between the pile and the soil, is examined.
