Response of axially loaded pile groups subjected to lateral soil movement - An expremental investigation

Abstract

A new experimental apparatus has been developed, which allows lateral soil movements and vertical load to be applied simultaneously on a pile. A number of tests have been undertaken, which offer consistent results. In this paper, a brief description of the apparatus was presented. Results from two model tests were reported, which were conducted on two instrumented pile groups embedded in sand subjected to uniform lateral soil movement. Preliminary analysis indicated that the increase in bending moment, shear force, soil reaction and the change of pile deflection mode due to axial load on the pile groups
