Static, rapid and dynamic one-dimensional compression tests were performed on four different sands at each of three different initial relative densities. The maximum stresses attained were generally 10,000 psi or higher, except for a low-pressure dynamic test series which attained stresses from 1,000 to 1,500 psi. The results of the tests are presented in the form of plots of axial stress versus axial strain, constrained modulus versus axial stress, and radial stress versus axial stress; grain size distribution curves are also presented for each specimen for both the before- and after-test conditions. The static data were compared to Hendron's static data or the same four sands; general agreement was noted, although the compressibility was consistently somewhat higher than observed by Hendron. The radial stresses were also somewhat lower; however, the discrepancies are probably a function of the test devices and the manner of performing the test. Crushing of the sand grains was very pronounced for the coarse sands, especially the angular sand, and had an overwhelming effect on the stress-strain relationship. Consideration of sand-grain contact stresses provides a qualitative explanation for the observed behavior.

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 comdition 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 stressstrain 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.

A general-purpose test facility for determining the one-dimensional compression characteristics of soils subjected to impulse-type loads has been developed in order to help satisfy the ever-increasing demand for reliable soil-property data required in support of a wide variety of nuclear-weapons-effects-related problems. The design, fabrication, installation, and evaluation of the various elements which together comprise the test facility were accomplished. The various considerations involved in the design and evaluation of the newly developed test facility are discussed in detail, thus providing some insight into the types of factors which affect the experimental-accuracy capability of a one-dimensional compression test facility and thereby the reliability of the data obtained under any particular set of conditions.

The ultimate purpose of this study of soil arching is to enable the economical design of reliable underground protective structures. Idealized small-scale structures were embedded in prepared specimens of dry sand, and long-duration, dynamic overpressures of various magnitudes up to 440 psi were applied to the surface of the sand. Foundation area and depth of soil cover over the structures were the primary variables during the tests. Measurements were made to evaluate the interrelationships between depth of soil cover, dynamic overpressure, soil stiffness, structural response, and soil arching. Soil arching over a particular soil-structure system subjected to dynamic loading was found to be a function of the geometry and the relative stiffness of that system. The geometry is accounted for by the perimeter-area ratio of the structure multiplied by the depth of the soil cover. The stiffness portion of the factor relates the soil stiffness to the stiffness of response of the structure relative to the free-field soil. (Author).

An experimental study of the relationship between pertinent wave-propagation parameters and the one-dimensional stress-strain behavior of two sands was conducted. The stress-strain relation for the sands was characterized by a nonlinear strain-hardening behavior. The nature of the stress-strain curve implied that shocks should form or be sustained in the soil. This phenomenon was studied by observing the dynamic and kinematic characteristics generated by a soft-fronted stress pulse applied at one end of a long slender column of laterally confined sand. To develop a method of predicting the kinematics of wave propagation from the stress-strain curve, the observed wave-propagation parameters were related to laboratory stress-strain curves. A unique sample container, loading system, and instrumentation system was developed. The experiments approximated one-dimensional conditions up to reflected stresses of 1,600 psi. The results indicated the shocking-up of the soft-fronted input pulse that could be predicted from the laboratory stress-strain curve. The particle-velocity versus wave-velocity relationships dictated the change in shape of the kinematic pulse and could be predicted using a secant modulus analysis technique. A very high stress versus time gradient (rise times less than 50 microsec) was observed to form as the wave propagated through the soil.
