Book Synopsis Correlations of Soil and Rock Properties in Geotechnical Engineering by : Jay Ameratunga
Download or read book Correlations of Soil and Rock Properties in Geotechnical Engineering written by Jay Ameratunga and published by Springer. This book was released on 2015-12-11 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a one-stop reference to the empirical correlations used extensively in geotechnical engineering. Empirical correlations play a key role in geotechnical engineering designs and analysis. Laboratory and in situ testing of soils can add significant cost to a civil engineering project. By using appropriate empirical correlations, it is possible to derive many design parameters, thus limiting our reliance on these soil tests. The authors have decades of experience in geotechnical engineering, as professional engineers or researchers. The objective of this book is to present a critical evaluation of a wide range of empirical correlations reported in the literature, along with typical values of soil parameters, in the light of their experience and knowledge. This book will be a one-stop-shop for the practising professionals, geotechnical researchers and academics looking for specific correlations for estimating certain geotechnical parameters. The empirical correlations in the forms of equations and charts and typical values are collated from extensive literature review, and from the authors' database.

This book was released on 2011-09-07 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2010 in the subject Engineering - Geotechnology, , course: Civil Engineering, language: English, abstract: With growing infrastructure developments in hilly areas and due to economical constraints of using locally available rockfill materials for construction of embankments, practicing engineers must be acquainted with geotechnical response of non-conventional granular soils. These materials are most likely to disintegrate with time due to physical and chemical weathering. In general, the laboratory investigations on durability characteristics of such materials are only made through simple slaking tests. However, studies examining the effects of slaking-induced disintegration of soil grains on the geotechnical engineering analysis and design parameters are rather limited. This is essentially due to the reason that the grains of standard laboratory sands are mostly durable and hence, the stress-strain response is considered to be unaffected by the presence of water. In order to explore the possible effects of deterioration of soil grains on static and dynamic properties of granular soils, a series of consolidated drained torsional shear tests on various crushed soft rocks were performed under saturated and dry conditions and compared with a well reported Toyoura silica sand consisting of durable grains. Due to the sensitivity of crushed rockfill to deteriorate upon water-submergence, test under dry conditions represented the response of a soil with intact grains, whereas a similar test under saturated condition simulated the potential reduction in strength and stiffness of the soil with time. From the grain size distributions determined after each test, a degradation index was defined to quantify the degree of disintegration of grains. Strength and deformation properties determined from monotonic as well as cyclic shear tests were then compared with this index. Possible correlations of water-induced deterioration of soil grains with consolidation behaviour, peak shear strengths, friction angles, dynamic shear stiffness, and volume-change characteristics during shearing were explored. In addition, the effects of confining stress and shear strain level on particle breakage were also investigated. It was concluded that time-dependent characterization of rockfill materials by monitoring the degree of deterioration can be helpful to avoid catastrophic geotechnical failures. Nonetheless, this study is a caution to conventional soil mechanics in which decay of grains and loss of soil strength with time are often uncared.

This book was released on 2018 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sandy and gravelly soils are encountered in many natural soil strata such as alluvial, fluvial, residual, and glacial deposits. These granular materials are used in the construction of many types of man-made geotechnical structures, fills, and ground improvements. A need exists to understand the dynamic behavior of these sandy and gravelly mixtures. A “binary packing model” has been proposed by some researchers to represent a simplified model for some sandy and gravelly soils that are composed of only a few, quite different, particle sizes (typically more than a factor of 20, and a factor of 34 used in this study) created during construction of geotechnical systems or in the natural environment. In other cases, gap-graded materials have been created. The packing condition and void distribution in the two types of gradations are complicated due to large variations in particle size and construction conditions. Up to now, no systematic studies have been conducted to evaluate key factors in the soil matrix (i.e., the parent materials in these mixtures) affecting the dynamic properties (i.e., shear modulus, G, and material damping ratio, D) of the binary and gap-graded mixtures considering the packing state of the matrix particles. In binary granular soils, estimating the critical packing condition, which represents the case when all void space between the large particles are completely filled with each group of small particles, is important. Additionally, the associated critical small-particle content (SPC*), which is the small-particle content (SPC) under the critical packing condition, can be calculated using the void ratios of the small-particle and large-particle materials. In this research, systematic variations of the parent materials in binary and gap-graded mixtures (i.e., the small and large particles in binary mixtures) were created, and the dynamic torsional resonant column (RC) testing was performed on a wide range of particle packing conditions. Some findings are: 1) the binary and gap-graded specimens for SPC ≥ 76% behaved very similarly to their parent poorly graded sand in both the small-strain and nonlinear dynamic properties; 2) the binary specimens for 15% ≤ SPC ≤ 100% showed a clear trend in the relationship of small-strain shear modulus at one atmosphere (A [subscript G]) and void ratio (e); 3) the binary specimens for 23% ≤ SPC ≤ 36%, which were in the range of SPC*, showed the highest stiffnesses and most nonlinearity; and 4) overall, the void ratio was a better parameter than the uniformity coefficient to estimate the nonlinear behavior of the specimens for 0% ≤ SPC ≤ 39%

Available in PDF, EPUB and Kindle. Book excerpt: The definitive guide to the critical issue of slope stability and safety Soil Strength and Slope Stability, Second Edition presents the latest thinking and techniques in the assessment of natural and man-made slopes, and the factors that cause them to survive or crumble. Using clear, concise language and practical examples, the book explains the practical aspects of geotechnical engineering as applied to slopes and embankments. The new second edition includes a thorough discussion on the use of analysis software, providing the background to understand what the software is doing, along with several methods of manual analysis that allow readers to verify software results. The book also includes a new case study about Hurricane Katrina failures at 17th Street and London Avenue Canal, plus additional case studies that frame the principles and techniques described. Slope stability is a critical element of geotechnical engineering, involved in virtually every civil engineering project, especially highway development. Soil Strength and Slope Stability fills the gap in industry literature by providing practical information on the subject without including extraneous theory that may distract from the application. This balanced approach provides clear guidance for professionals in the field, while remaining comprehensive enough for use as a graduate-level text. Topics include: Mechanics of soil and limit equilibrium procedures Analyzing slope stability, rapid drawdown, and partial consolidation Safety, reliability, and stability analyses Reinforced slopes, stabilization, and repair The book also describes examples and causes of slope failure and stability conditions for analysis, and includes an appendix of slope stability charts. Given how vital slope stability is to public safety, a comprehensive resource for analysis and practical action is a valuable tool. Soil Strength and Slope Stability is the definitive guide to the subject, proving useful both in the classroom and in the field.

This book was released on 2019-08-20 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides essential insights into recent developments in fundamental geotechnical engineering research. Special emphasis is given to a new family of constitutive soil description methods, which take into account the recent loading history and the dilatancy effects. Particular attention is also paid to the numerical implementation of multi-phase material under dynamic loads, and to geotechnical installation processes. In turn, the book addresses implementation problems concerning large deformations in soils during piling operations or densification processes, and discusses the limitations of the respective methods. Numerical simulations of dynamic consolidation processes are presented in slope stability analysis under seismic excitation. Lastly, achieving the energy transition from conventional to renewable sources will call for geotechnical expertise. Consequently, the book explores and analyzes a selection of interesting problems involving the stability and serviceability of supporting structures, and provides new solutions approaches for practitioners and scientists in geotechnical engineering. The content reflects the outcomes of the Colloquium on Geotechnical Engineering 2019 (Geotechnik Kolloquium), held in Karlsruhe, Germany in September 2019.
