A METHOD OF DETERMINATION OF K - THE LATERAL EARTH PRESSURE COEFFICIENT FOR SHAFT FRICTION

The author discusses the limitations of the "static formula" and derives a theoretical expression for k taking into account the stress distribution around piles requiring detailed stress measurements and sophisticated studies. He assumes that the vertical effective stress adjacent to the pile shaft remains constant up to failure. Two equations for the shaft resistance are derived assuming failure takes place at the interface between the soil and the shaft. There is good agreement between predicted and values of K measured by J B Burland although the predictions assume that the failure takes place on a horizontal plane. No reason is given for the adoption of the horizontal plane as a failure plane as opposed to any other. /TRRL/
