Model Tests on Single Piles Subjected to Lateral Soil Movement

摘要

The paper describes a series of laboratory tests on single instrumented modelpiles embedded in calcareous sand undergoing lateral movement. Key parameters influencing the maximum bending moment in the pile for a constant soil density have been identified to be pile head fixity condition, the ratio of the depth of moving soil to the pile embedded length, and pile diameter and stiffness. Normalized expressions for maximum bending moment are also presented. The agreement between the experimental results and the theoretical predictions by an existing boundary element program is shown to be reasonably good.
