Limiting pressure on a laterally loaded pile in a frictional soil

Limiting pressure on a laterally loaded pile in a frictional soil
This Letter investigates by means of finite difference analyses the ultimate lateral pressure developed on a pile moving through a soil whose strength is characterised by an effective angle of shearing resistance (phi'). Analyses were carried out to determine the distribution of ultimate pressure with depth, with particular attention paid to nearsurface effects, for a value of (phi') representative of a clay soil. The model results are compared with popular empirical distributions of ultimate lateral pressure, obtained generally from full scale and model tests in sand. It was found that the depth to which the unconfined ground surface affects the ultimate lateral pressure developed is consistently about 5 m. Below the zone influenced by the surface effects, limiting lateral pressures were found to increase linearly with depth. The empirical distributions for the limiting pressure were found to bracket the numerical results for a frictionless pile-soil interface, and underestimate the numerical results for a full strength pile-soil interface.

Abstract

This Letter investigates by means of finite difference analyses the ultimate lateral pressure developed on a pile moving through a soil whose strength is characterised by an effective angle of shearing resistance (phi'). Analyses were carried out to determine the distribution of ultimate pressure with depth, with particular attention paid to nearsurface effects, for a value of (phi') representative of a clay soil. The model results are compared with popular empirical distributions of ultimate lateral pressure, obtained generally from full scale and model tests in sand. It was found that the depth to which the unconfined ground surface affects the ultimate lateral pressure developed is consistently about 5 m. Below the zone influenced by the surface effects, limiting lateral pressures were found to increase linearly with depth. The empirical distributions for the limiting pressure were found to bracket the numerical results for a frictionless pile-soil interface, and underestimate the numerical results for a full strength pile-soil interface.
