Model Tests on Pile Groups Subjected to Lateral Soil Movement

摘要

This paper describes a series of model tests on instrumented pile groups embeddedin calcareous sand undergoing later movement. The extent of the group effect on the lateral response of a pile in a group was found to be dependent on a number of factors, including the position of the pile in the group, the pile spacing, the number of piles, and the head fixity condition. The agreement between the experimental element program is shown to be reasonably good, provided that appropriate parameters are adopted.
