Book Soil Quality for Crop Production and Ecosystem Health

Download or read book Soil Quality for Crop Production and Ecosystem Health written by E.G. Gregorich and published by Elsevier. This book was released on 1997-11-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.

Book Influence of Compaction Energy on Soil Engineering Properties

Download or read book Influence of Compaction Energy on Soil Engineering Properties written by Isaac Robert Drew and published by . This book was released on 2005 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strength and deformation parameters of compacted soil are known to be related to soil type and moisture content. However, little attention has been directed towards understanding the influence of compaction energy on these properties. This paper describes laboratory and field studies conducted to evaluate the relationship between soil type, soil moisture content, and compaction energy on seven cohesive soil types. In the lab, specimens were compacted with impact energy at levels of 355, 592 (standard Proctor), 987, 1643, and 2693 kJ/m3 (modified Proctor) over a wide range of moisture contents to determine dry unit weight, unconfined compressive strength and the secant (50 percent strain) stiffness. In total, 175 Proctor tests and 95 unconfined compression tests were performed. At each energy level, a soil was tested at 4 to 5 moisture contents with respect to its standard Proctor moisture range. In addition, 54 consolidated undrained triaxial tests were performed at the five energies and four moisture contents for one soil to evaluate changes in effective stress shear strength parameters. This paper summarizes the results of statistical analyses performed on all lab and field tests conducted. The models that best explain variability in dry unit weight, strength, and stiffness are presented. Models are presented individually for each soil type and also inclusive of all soils grouped together. Independent variables used in the modeling include compaction energy, moisture content, confining pressure, Atterberg limits, material passing the No. 200 sieve, and clay fraction. In addition, a new compaction model, derived from a linear rate equation, is presented and checked for validity in estimating soil dry unit weight as a function of compaction energy. Results indicate that compaction energy, combined with moisture content, is a key factor in determining soil strength and stiffness parameters. It is concluded that the strength and stability of a compacted soil cannot be assessed in terms of relative compaction alone. Instead, this research encourages the use of strength and stiffness in the design and construction phases of earthwork operations, being the true functional requirements for compaction specifications.

Book A Geology for Engineers

Download or read book A Geology for Engineers written by F.G.H. Blyth and published by CRC Press. This book was released on 2017-12-21 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: No engineering structure can be built on the ground or within it without the influence of geology being experienced by the engineer. Yet geology is an ancillary subject to students of engineering and it is therefore essential that their training is supported by a concise, reliable and usable text on geology and its relationship to engineering. In this book all the fundamental aspects of geology are described and explained, but within the limits thought suitable for engineers. It describes the structure of the earth and the operation of its internal processes, together with the geological processes that shape the earth and produce its rocks and soils. It also details the commonly occurring types of rock and soil, and many types of geological structure and geological maps. Care has been taken to focus on the relationship between geology and geomechanics, so emphasis has been placed on the geological processes that bear directly upon the composition, structure and mechanics of soil and rocks, and on the movement of groundwater. The descriptions of geological processes and their products are used as the basis for explaining why it is important to investigate the ground, and to show how the investigations may be conducted at ground level and underground. Specific instruction is provided on the relationship between geology and many common activities undertaken when engineering in rock and soil.

Book Correlations of Soil and Rock Properties in Geotechnical Engineering

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.

Book Effect of Rock Content on Compaction Characteristics of Clayey Gravel

Download or read book Effect of Rock Content on Compaction Characteristics of Clayey Gravel written by Bernard B. Gordon and published by . This book was released on 1965 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper contains results of compaction studies which have been conducted by the California Department of Water Resources on the very rocky soil selected for the impervious core of the Oroville Dam in California. The material studied was a clayey sand to clayey gravel containing a percentage of plus No. 4 U. S. Standard sieve size varying up to 65 per cent by dry weight of total sample. Considerable attention was paid to effect on compaction characteristics of varying maximum particle size, mold diameter, and hammer size and weight. Comparisons were made between the moisture-density relationship as determined by test and as computed using a theoretical rock correction factor. Families of curves were developed which showed the influence of moisture content of the minus No. 4 fraction on total sample dry density. The test results support findings by others that total sample maximum densities deviate from theoretically computed values based on the soil fraction at relatively low rock contents. For tests on the minus 1 1⁄2-in. fraction, however, a very small correction factor is needed. The plasticity of the soil fraction is shown to have a noticeable effect on the total sample maximum density.
