This book was released on 1994 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several laboratory studies have shown that the hydraulic conductivity of compacted clay may increase up to three orders of magnitude when subjected to freeze-thaw. In this paper, methods to freeze and thaw specimens of compacted clay are reviewed and compared. Methods to measure the hydraulic conductivity of the specimens are also reviewed. Only naturally formed clay soils are considered; soil-bentonite mixtures and other amended soils are not included.

This book was released on 2012-11-09 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freezing and thawing of soils is a common phenomenon in the winter-cold zone. The thesis titled “Material Cycling of Wetland Soils Driven by Freeze-Thaw Effects” systematically explores the freeze-thaw effects on the accumulation and release processes of carbon and nitrogen in wetland soils, which is a good step toward the investigation of biogeochemical processes in wetlands in seasonal freeze-thaw areas. It is also developing strategies aimed at global warming effects on the accumulation and release of carbon and nitrogen in wetlands. Dr. Xiaofei Yu works at the Northeast Institute of Geography and Agroecology, Chinese Academy of Sciences, China.

Download or read book Fundamentals of Geoenvironmental Engineering written by Abdel-Mohsen O. Mohamed and published by Butterworth-Heinemann. This book was released on 2017-10-31 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Geoenvironmental Engineering: Understanding Soil, Water, and Pollutant Interaction and Transport examines soil-water-pollutant interaction, including physico-chemical processes that occur when soil is exposed to various contaminants. Soil characteristics relevant to remedial techniques are explored, providing foundations for the correct process selection. Built upon the authors' extensive experience in research and practice, the book updates and expands the content to include current processes and pollutants. The book discusses propagation of soil pollution and soil characteristics relevant to remedial techniques. Practicing geotechnical and environmental engineers can apply the theory and case studies in the book directly to current projects. The book first discusses the stages of economic development and their connections to the sustainability of the environment. Subsequent chapters cover waste and its management, soil systems, soil-water and soil-pollutant interactions, subsurface transport of pollutants, role of groundwater, nano-, micro- and biologic pollutants, soil characteristics that impact pollution diffusion, and potential remediation processes like mechanical, electric, magnetic, hydraulic and dielectric permittivity of soils. - Presents a clear understanding of the propagation of pollutants in soils - Identifies the physico-chemical processes in soils - Covers emerging pollutants (nano-, micro- and biologic contaminants) - Features in-depth coverage of hydraulic, electrical, magnetic and dielectric permittivity characteristics of soils and their impact on remedial technologies

Download or read book Soil Structure written by Bobby A. Stewart and published by CRC Press. This book was released on 1995-06-13 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil Structure offers a multidisciplinary approach to the study of soil structure and its relevance to wide ranging investigations in environmental sciences. Topics covered in Soil Structure include soil structure determination, soil fabric genesis and functions, strength and stress distribution, fabric changes in plastic clays, the effects of organic matter and earthworms, air slaking, and hydraulic conductivity changes. The book also discusses litter decomposition and matter transport, the characterization of pore organization, monitoring via a neutron activated tracer, various influences on growth and phosphorus supply of plants and on water uptake by plants, the effects of acidification, and much more. Improved procedures for measuring and calculating the unsaturated hydraulic conductivity of structured soils are also given.

This book was released on 1995 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis evaluates the effects of freeze-thaw weathering, drying-wetting weathering, and changes in pore fluid chemistry on the hydraulic conductivity of highly plastic Lake Agassiz clay. Lake Agassiz clay is frequently considered as a cost-effective alternative to geosynthetic membranes and liners for use in waste containment structures, as well as a natural barrier beneath contaminated sites. Four types of freeze-thaw weathering tests were conducted with each type differing by the temperature conditions imposed and the availability of water. Three methods of drying and wetting were used and were differentiated by the presence or absence of an artificial crack. Chemical tests involved the addition of varying concentrations of sodium carbonate solutions after weathering to reduce hydraulic conductivities, while other chemical permeation tests were conducted using dimethyl sulfoxide as a method of reducing the effects of freeze-thaw weathering. The equipment, specimen processing procedures and test methodology are described in detail. The results indicate that freeze-thaw weathering and specimens artificially cracked after desiccation produced an order of magnitude increase in hydraulic conductivity of Lake Agassiz clay. A slight decrease occurred in specimens which were subjected to desiccation then rewetting before permeation. Self-sealing was incomplete after each weathering process because consolidation of soil aggregates had occurred due to various suctions generated during weathering. A comparison between hydraulic conductivity values obtained ftom oedometer tests and those obtained from triaxial hydraulic conductivity tests was also performed. Results indicate that the triaxial test apparatus is a superior method for determining the hydraulic conductivity of natural clay specimens.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is concerned with sites on, or below, which there has been previous industrial activity leading to some permanent effects on the ground. A wide range of problems and impacts makes treatment of contaminated and derelict land a very complex issue. This volume presents the proceedings of Green 2, the second in a four-yearly series of international symposia that discuss aspects of geotechnical engineering intimately related to the environment.

Download or read book Dynamics of Freezing Thawing Soil around Subway Shield Tunnels written by Zhen-Dong Cui and published by Springer Nature. This book was released on 2020-05-18 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses development laws for axial strain and excess pore water pressure in silty clay around subway shield tunnels before and after freezing-thawing when subjected to subway loading, as well as the effect of freezing-thawing on the dynamic parameters of silty clay, including the dynamic modulus and damping ratio, introducing readers to the design and construction of bypasses in subway tunnels with the artificial freezing method. On this basis, it then studies the microstructures of silty clay before and after freezing-thawing cyclic loading by means of scanning electron microscope tests and mercury intrusion porosimetry tests. Lastly, the book presents a numerical simulation of the dynamics of silty clay around subway tunnels before and after thawing. Given its scope, it offers a valuable reference guide for construction researchers and designers alike, as well as senior undergraduate and graduate students at colleges and universities.
