Size and Shape of Tamper's Base in Dynamic Compaction of Loose Sands

摘要

The design of dynamic compaction is largely based on experience. A review of the literature discovers that the base area of the tamper has not been considered in design and the tampers used in the published case histories all have a flat base. This paper presents the results of a study to show that both size and shape of the base of the tamper are significant in soil improvement by dynamic compaction. Both theoretical analyses and laboratory model tests were carried out during this study.
