This book was released on 1985-01-01 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prepared by the Technical Council on Cold Regions Engineering of ASCE. The design of engineering projects in frozen ground requires thermal design considerations in addition to standard geotechnical design. Factors that influence the thermal characteristics of a site include climatological data, microclimatic characteristics, local hydrology, soil properties, and disturbance. This monograph presents ground temperature observations, procedures for temperature monitoring, analytical methods for ground thermal regime calculations, and ground thermal properties. Active and passive techniques for ground temperature control and ground thawing methods are also presented, followed by case histories of ground temperature effects.

Download or read book Chemical Aspects of Soil Freezing written by Karen S. Henry and published by . This book was released on 1988 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil water chemistry and soil particle characteristics directly and significantly influence the freezing process in soils. The rate of frost heave is influenced because chemicals modify water migration and depress the freezing point in soils. Solutes are concentrated when they are expelled from crystallizing ice, modifying adsorbed film thicknesses, depressing freezing points, creating concentration gradients, altering forces between particles or between ice particles, and modifying the chemical potential of the water. These effects often have counteracting influences on frost heave. Solute expulsion during freezing produces a 'fringe-like' freezing front in saline soils, primarily because of freezing point depression; this may also be true in 'non-saline' soils. Heave can be reduced by adding chemicals to soil to depress the freezing point to modify the soil's structure or hydraulic characteristics. The concentration of solutes in the unfrozen water of the freezing soil can possibly be used for isolating toxic wastes in soil. Ground freezing, Soils, Soil chemistry, Soil freezing. (mjm).

Book excerpt: Developments in Geotechnical Engineering Volume 26: Ground Freezing presents the proceedings of the First International Symposium on Ground Freezing, held in Bochum, Germany on March 8-10, 1978. It summarizes progress in the application of the ground freezing technique in geotechnical engineering, with a focus on engineering with frozen soils and related frost research problems. It includes papers that discuss phase transformation of water, thermodynamics, heat and mass transfer, and mathematical models. The laboratory and theoretical studies of thermophysical and mechanical properties are discussed as well. Organized into 43 chapters, this volume begins with an overview of the freezing and thawing of soils, earth, and rock, and the engineering applications of the favorable properties of frozen ground. It then discusses the mechanical properties of artificially frozen soil for construction purposes, the principles of mechanical and thermal behavior of frozen soil, and the design and calculation of frozen soil-structures. Furthermore, it explains the calculation and dimensioning of refrigeration plants and monitoring of frost penetration. The methods and instrumentation for determining the locations of boundaries of frozen soils and the factors affecting the formation of soil cryogenic textures upon artificial active and passive soil freezing are described. The book also details the influence of salts in the pore water in freezing soils and explains how clay microstructure affects the amount of unfrozen water. In addition, it presents the physicomechanical and thermomechanical properties of frozen coarse-grained soil with sandy clay aggregate. This book will be a valuable source of information for scientists and engineers.

Download or read book Some Strength Properties of Frozen Soil and Effect of Loading Rate written by C. W. Kaplar and published by . This book was released on 1971 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report presents frozen soil strength data for several soil types. The data include the effects of unit dry weight and the degree of saturation on the strength of frozen soils. The frozen soil strength increases with moisture content (frozen) up to full saturation and then drops off at greater ice contents. Data are presented showing that the compressive strength of many materials, frozen (including sea ice) and non-frozen, is greater under rapid loading rates. Fresh water ice shows the opposite effect Values of the adfreeze bond of frozen soils to various materials are also presented. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Paper 1: Three soils, including a silt, silty clay, and clay-like soil, were used in this study. Specimens were molded using varying percentages of calcium chloride as an admixture and freezing-and-thawing tests were made at freezing temperatures of 24F and -18F. Paper 2: A preliminary report is given on a new method of determination of frost in the soil profile in situ. The method involves interpretation of electrical resistances obtained with a soil-moisture block and their associated soil temperatures. Paper 3: This paper summarizes the results of laboratory and field investigations, made during the last 4 years, to determine ways of controlling footing heave.

Download or read book An Introduction to Frozen Ground Engineering written by Orlando B. Andersland and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frozen Ground Engineering first introduces the reader to the frozen environment and the behavior of frozen soil as an engineering material. In subsequent chapters this information is used in the analysis and design of ground support systems, foundations, and embankments. These and other topics make this book suitable for use by civil engineering students in a one-semester course on frozen ground engineering at the senior or first-year-graduate level. Students are assumed to have a working knowledge of undergraduate mechanics (statics and mechanics of materials) and geotechnical engineering (usual two-course sequence). A knowledge of basic geology would be helpful but is not essential. This book will also be useful to advanced students in other disciplines and to engineers who desire an introduction to frozen ground engineering or references to selected technical publications in the field. BACKGROUND Frozen ground engineering has developed rapidly in the past several decades under the pressure of necessity. As practical problems involving frozen soils broadened in scope, the inadequacy of earlier methods for coping became increasingly apparent. The application of ground freezing to geotechnical projects throughout the world continues to grow as significant advances have been made in ground freezing technology. Freezing is a useful and versatile technique for temporary earth support, groundwater control in difficult soil or rock strata, and the formation of subsurface containment barriers suitable for use in groundwater remediation projects.
