Abstract

Dynamic penetration tests, such as the standard penetration test, are widely used in conjunction with empirical or ad hoc relationships to determine the compressibility of granular soil under foundations. This Paper reviews those factors which control the compressibility of sand, and those which are thought to influence dynamic penetration resistance. The results of a laboratory study of the compressibility and dynamic penetration resistance of an uniform fine sand at a single density are presented. It is shown that while the compressibility of the sand is strongly dependent on its previous stress path, and is relatively unaffected by its current stress level, dynamic penetration resistance is strongly influenced by current stress level and is unaffected by stress path.
