FAILURE MODES OF SAND SURROUNDING A LATERALLY DISPLACED PILE SUBJECTED O STATIC AND IMPACT LOADS.
Abstract
An experimental investigation has been conducted to define the patterns of soil movement in the vicinity of a laterally displaced pile under static and impact loadings. A 2-in.-square, 30-in.-long stiff model pile section was embedded 18 inches into a box of uniform dry sand which had a colored grid pattern. The pile was loaded laterally; the sand was wetted, allowed to drain, and was vertically sectioned to photographically record the characteristic patterns of sand movement. The data reveal that the horizontal sand movement about the lower portions of the embedded pile are similar for both static and impact loadings, but that impact loadings produce larger sand movements near the surface. Influence values and volume factors for the sand motion in the vicinity of the pile are given for both static and impact loads. Inertial pile loading, developed as a consequence of the soil movement, can be determined from these quantities. (Author)
