The elastic buckling characteristics of a slender model pile embedded in soft clay have been investigated for both static and vibratory loading conditions. The load-rotation behaviour was studied for a static eccentric load. Comparative tests were carried out with vertical vibrations imposed directly on the pile in order to simulate the field situation in which the vibrations originate from a pile supported structure. It was found that the pile buckling characteristics as measured by both the ultimate load and the elastic critical load were not significantly altered by the presence of vibrations. From considerations of a possible scaling law from model to prototype it was found that different conclusions regarding possible prototype behaviour could be drawn depending upon the method used for the measure of vibration severity. Measurements of field vibrations produced by traffic found were to yield quite low vibration severities, but it is possible that more severe vibrations could occur in other field situations.
