This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Proper soil characterization requires a combination of laboratory and in-situ testing to gather insight into soil properties, their spatial extent, and various engineering parameters of interest at the project site. The assessment of sample disturbance for intermediate soils and quantifying spatial variability in site investigation using a transition probability geostatistical approach is addressed herein. A laboratory study is presented to quantify the response of intermediate soils subjected to various levels of sample disturbance. Results indicate clay-based sample disturbance criteria are not applicable to low plasticity soils, due in part to in changes in soil compressibility. A work-based approach is used to demonstrate Cr/Cc captures sample disturbance that is independent of plasticity, overburden stress, and OCR. Systematic investigation of these effects requires consistent preparation methodology across a range of fine-grained intermediate soils. A slurry preparation methodology for preparing reconstituted mixtures of fine-grained, intermediate soils across a range of plasticity from nonplastic to high plasticity soils was developed. The approach presented herein produces uniform samples with repeatable oedometer consolidation, monotonic triaxial compression, monotonic simple shear, and cyclic simple shear behavior. Separately, nonplastic silts and low plasticity silty clays prepared via acid dissolution provides a mechanism for systematically investigation of fabric effects in the laboratory. Acid dissolution of an admixed finely ground carbonate soil is shown to increase the state parameter for nonplastic silt resulting in changes to undrained shearing response from dilative to contractive behavior, while low plasticity silty clay under the same process does not form measurable structure nor results in changes to state parameter, suggesting the particle dissolution method using acid may be limited to nonplastic soils. Site characterization is a process used in part to assess and extend discrete observations from in-situ testing, sampling, and lab testing. This process is amenable to geostatistical approaches, where the role of geostatistics is to extend what is known from discrete sampling to unsampled locations. Geostatistical simulations are used to directly map anticipated zones of subsurface liquefaction for a spatially variable project site. Development of robust geostatistical simulations requires an understanding of the interrelationship between the number of sampling locations, subsurface correlation structure, separation distance, and extent of site coverage. Discussion of these effects and the ability to capture correlation structure and produce realistic subsurface simulations is shown using an idealized example and an industry project site.

Download or read book Geostatistical Applications for Precision Agriculture written by Margaret A. Oliver and published by Springer Science & Business Media. This book was released on 2010-07-27 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to bring together a series of contributions from experts in the field to cover the major aspects of the application of geostatistics in precision agriculture. The focus will not be on theory, although there is a need for some theory to set the methods in their appropriate context. The subject areas identified and the authors selected have applied the methods in a precision agriculture framework. The papers will reflect the wide range of methods available and how they can be applied practically in the context of precision agriculture. This book is likely to have more impact as it becomes increasingly possible to obtain data cheaply and more farmers use onboard digital maps of soil and crops to manage their land. It might also stimulate more software development for geostatistics in PA.

Download or read book Engineering of Glacial Deposits written by Barry G. Clarke and published by CRC Press. This book was released on 2017-07-14 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: At some time 30% of the world’s land mass was covered by glaciers leaving substantial deposits of glacial soils under major conurbations in Europe, North and South America, New Zealand, Europe and Russia. For instance, 60% of the UK has been affected, leaving significant glacial deposits under major conurbations where two thirds of the population live. Glacial soils are composite soils with significant variations in composition and properties and are recognised as challenging soils to deal with. Understanding the environment in which they were formed and how this affects their behaviour are critical because they do not always conform to classic theories of soil mechanics. This book is aimed at designers and contractors working in the construction and extractive industries to help them mitigate construction hazards on, with or in glacial deposits. These soils increase risks to critical infrastructure which, in the UK includes the majority of the road and rail network, coastal defences such as the fastest eroding coastline in Europe and most of the water supply reservoirs. It brings together many years of experience of research into the behaviour of glacial deposits drawing upon published and unpublished case studies from industry. It draws on recent developments in understanding of the geological processes and the impact they have upon the engineering properties, construction processes and performance of geotechnical structures. Unlike other books on glaciation it brings together all the relevant disciplines in earth sciences and engineering to make it directly relevant to the construction industry.

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.
