Available in PDF, EPUB and Kindle. Book excerpt: Ground motion prediction formulas based upon elastic wave propagation in one-dimension (no strain transverse to the propagation direction) have been used widely in protective construction work. Actual soil materials exhibit many deviations from elastic behavior. This report assesses the probable influence of these non-elastic effects upon the accuracy of the above-mentioned prediction formulas, and upon the question of stress attenuation with depth. Three different models of soil behavior are assumed: a standard 3-element visco-elastic model (spring in series with spring-dashpot combination); a compacting model (straight line loading and unloading curves); and an ''elastic'' model in which any arbitrary shape may be assigned to the loading stress-strain curve. This report deals primarily with the first of these three models; the possible significance and probable importance of the third model are discussed briefly. By combining the theoretical and experimental results, it is shown that the elastic ground motion prediction formulas are generally valid (for cases where it is appropriate to think of one-dimensional motion); i.e. the possible effects of viscosity and inelasticity are no greater than uncertainties as to the order of magnitude of the compressibility of an in situ soil mass.

This book was released on 1968 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Uniaxial Stress-Strain Behavior of Unsaturated Soils at High Strain Rates by :
Download or read book Uniaxial Stress-Strain Behavior of Unsaturated Soils at High Strain Rates written by and published by . This book was released on 1994 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Split-Hopkinson Pressure Bar was used to study the uniaxial stress-strain behavior of compacted moist soils under one-dimensional, undrained, confined compression loading at high strain rates (1000/sec and 2000/ sec. Three soils, Eglin Sand, Tyndall sand and Ottawa 20-20 sand were tested. The results suggest that the stress strain response is dominated by the water- phase from the lock-up strain and beyond. The soil skeleton dominates the response from the start of loading up to the lock-up strain. It appears that there may be some strain-rate effects, however, the data arc insufficient to adequately demonstrate this and further investigation is suggested. The research described in this report has demonstrated that the Split-Hopkinson Bar System is a viable technique for high strain rate dynamic geotechnical testing of unsaturated, saturated, and dry soils, and provides a framework for conducting further studies.

Book Synopsis Deformation Characteristics of Geomaterials by : C.-K. Chung
Download or read book Deformation Characteristics of Geomaterials written by C.-K. Chung and published by IOS Press. This book was released on 2011 with total page 1382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the international edition of the proceedings of IS-Seoul 2011, the Fifth International Symposium on Deformation Characteristics of Geomaterials, held in Seoul, South Korea, in September 2011.The book includes 7 invited lectures, as well as 158 technical papers selected from the 182 submitted. The symposium explored ideas about the complex load-deformation response in geomaterials, including laboratory methods for small and large strains; anisotropy and localization; time-dependent responses in soils; characteristics of treated, unsaturated, and natural geomaterials; applications in field methods; evaluation of field performance in geotechnical structures; and physical and numerical modeling in geomechanics. These topics were grouped under a number of main themes, including experimental investigations from very small strains to beyond failure; behavior, characterization and modeling of various geomaterials; and practical prediction and interpretation of ground response: field observation and case histories. Both the symposium and this book represent an important contribution to the exchange of advanced knowledge and ideas in geotechnical engineering and promote partnership among participants worldwide.
Book Synopsis A Study of the Behavior of Soil and Rock Subjected to High Stress Levels by : E. W. Brooker
Download or read book A Study of the Behavior of Soil and Rock Subjected to High Stress Levels written by E. W. Brooker and published by . This book was released on 1965 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical and experimental investigation has been conducted to study the behavior of sand and clay under high stresses. The analytical work developed equations for the stress-strain properties of a medium composed of elastic equi-radii spheres in a face-centered cubic array. Theoretical relationships between the coefficient of earth pressure at rest, the angle of internal friction, and the coefficient of friction between the spheres were also derived. A special zero-lateral-strain device was developed for one-dimensional compression tests on sand and clay. The tests were carried to axial stresses of 3300 psi on four sands and 2200 psi on five remolded clays. The tests on sand demonstrated that the grain shape and gradation were as important as relative density in influencing the stress-strain properties. Controlled radial strain tests on the sand, with axial stresses up to 5000 psi, disclosed a failure envelope with a significant decrease in slope under the high pressures. Unloading of the sands and clays caused the coefficient of earth pressure at rest to increase and approach the coefficient of passive earth pressure. (Author).

Book Synopsis Consolidation Analyses of Soils by : Jian-Hua Yin
Download or read book Consolidation Analyses of Soils written by Jian-Hua Yin and published by CRC Press. This book was released on 2020-12-28 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: When stresses are applied to saturated soil, deformation will occur as water in voids is squeezed out. Consolidation Analyses of Soils focuses on the consolidation of fully saturated soils. The book follows a classic approach by beginning with one-dimensional constitutive relations of soils and one-dimensional consolidation. It then moves on to analytical solutions to several one-dimensional consolidation problems and one-dimensional finite strain consolidation. The authors also present a finite element method for consolidation analysis of one-dimensional problems, analytical solutions to consolidation of soil with vertical drains, and a finite difference method for consolidation analysis of one-dimensional problems. Simplified methods for consolidation analysis of soils exhibiting creep are introduced and applied to different cases. Three-dimensional consolidation equations and solutions of typical three-dimensional consolidation problems are covered, as well as simplified finite element consolidation analysis of soils with vertical drain and finite element method for three-dimensional consolidation problems. The book is unique in that it covers both classic solutions and state-of-the-art work in consolidation analyses of soils. Authors Jian-Hua Yin is Chair Professor of Soil Mechanics in the Department of Civil and Environmental Engineering at The Hong Kong Polytechnic University. Guofu Zhu is a Professor in the Department of Engineering Structures and Mechanics at Wuhan University of Technology, China.
