Download or read book Remote Field Methods to Measure Frost Depth written by CH. Benson and published by . This book was released on 1999 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reviews the three common methods used to remotely measure frost depth: (1) soil temperature measurements, (2) soil electrical resistivity measurements, and (3) soil dielectric constant measurements. Soil temperature measurements are often made using thermocouples or thermistors. Specially designed probes are used to measure frost depth based on electrical resistivity. Inferences based on dielectric constant are usually made using time domain reflectometry. Frost depths based on soil temperatures are made equally well using thermistors or thermocouples. However, frost depths inferred from soil temperature measurements can be erroneous if the freezing point is depressed (due to unsaturated conditions or the presence of salts) or if the temperature profile is essentially isothermal and near 0°C. More reliable measurements of frost depth are made using electrical resistivity or dielectric constant measurements because the electrical properties of soil are affected more by phase change of the pore water than temperature.

Download or read book Field Techniques for Sea Ice Research written by Hajo Eicken and published by University of Alaska Press. This book was released on 2010-03-15 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: As much as one-tenth of the world’s oceans are covered with sea ice, or frozen ocean water, at some point during the annual cycle. Sea ice thus plays an important, often defining, role in the natural environment and the global climate system. This book is a global look at the changes in sea ice and the tools and techniques used to measure and record those changes. The first comprehensive research done on sea-ice field techniques, this volume will be indispensable for the study of northern sea ice and a must-have for scientists in the field of climate change research.

Download or read book Instrumentation for Measurement of Moisture written by L. F. Ballard and published by Highway Research Board. This book was released on 1973 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to evaluate the suitability of existing instrumentation and techniques and to stimulate development of modified or new procedures to measure the amount and state of water in highway components, such as embankments, subgrades, base courses, pavements, and structures. In accomplishing this objective, the researchers conducted an extensive literature review. Those techniques that appear to be immediately applicable to highway problems were evaluated using a linear decision model for comparing instrument performance characteristics with specific moisture measurement needs. A comprehensive list of performance characteristics with which to make this comparison was compiled.
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.
