THE BEHAVIOR OF SAND IN ONE-DIMENSIONAL COMPRESSION

Abstract

The behavior of sand in one-dimensional compression is investigated with both theoretical and experimental studies. The phenomenological aspects of one-dimensional behavior are discussed, such as stress-strain characteristics, energy absorption capacity, and coefficient of earth pressure at rest. The analytical study deals with the stress-strain relations of an idealized granular medium composed of elastic, equi-radii spheres in a face-centered cubic array. A new solution is derived for the behavior of the array when subjected to a monotonically increasing axial compressive stress for the condition of zero radial strain. An experimental device is described which is capable of measuring the radial stresses developed in high-pressure, one-dimensional tests. Measurements of both the coefficient of earth pressure at rest and stress strain properties are presented for four sands tested to an axial stress of 3,290 psi. Correlations are presented which compare the actual behavior of a rounded, uniform, quartz sand in one-dimensional and triaxial compression with the behavior suggested by the theoretical analysis.
