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.

The study deals with experiments in drive sampling in frozen ground for the recovery of undisturbed soil samples. The drive-sampling experiments discussed in this paper were performed in frozen, fine-grained soils consisting of silts, clays, and fine sand. In addition, the drive sampling was performed in permafrost having temperatures ranging from approximately 29 to 31.5 degrees Fahrenheit. The drive method of sampling consists essentially of driving a tube or sampler into the soil and recovering the soil that enters the sampler as a result of the driving action. Driving of the sampler and subsequent withdrawal may be accomplished by power equipment or by manual procedures depending on the depth of the exploration. (Author).

This new edition of Frozen Ground Engineering gives a peerless presentation of soil mechanics for frozen ground conditions and a variety of frozen ground support systems used on construction projects worldwide. An authoritative update of the industry standard, this Second Edition covers the essential theory, applications, and design methods using frozen ground in the construction of deep shafts, tunnels, deep excavations, and subsurface containment barriers. New material features design models for pavement structures used in seasonal frost and permafrost areas, new information on the movement of fluid phase contaminants in frozen ground, and helpful appendices offering guidance on common frozen ground tests and SI unit conversions. This new edition gives the essential information engineers, geologists, and students need in a complete reference, including up-to-date information on: Sensitivity of frozen ground to climate change Experimental work on frozen soil creep and strength Monitoring creep in frozen slopes Frost protection of foundations using ground insulation Highway insulation Load restrictions for seasonal frost areas

The problems of obtaining frozen samples by core drilling of perennially frozen gravel and rock were investigated. Most of the core drilling was carried out in ice-bonded, well-graded alluvial gravel with the ground temperature near its freezing point. Both chilled compressed air and oil-based liquids were used as drilling fluids. The details of both successful and unsuccessful coring attempts are reported and related to descriptions and photographs of samples of a wide range of quality. Drilling variables such as weight on the bit, rotational velocity, rate of penetration, fluid temperatures, viscosities, flow rates and pressures and mechanical details of the diamond bits are reported.

First published in 1991. This volume presents a brief description of the natural conditions of the permafrost regions, the properties of the permafrost and the processes occurring in it, the fundamentals of the heat transfer processes during drilling and the service temperature conditions of the tool. Methods and devices for cooling the flushing media, principles of quality control of flushing agents and the technology and commercial viability of their use during drilling in the permafrost have been considered. The main emphasis in this book is on the drilling technology which uses a variety of flushing agents. The text also includes a description of the technology of utilizing grouting solutions, the theory and practice of drilling with simultaneous freezing of weakly cohesive, moist ground as well as jdrilling holes in the ice-sheets of the circumpolar regions. This book is intended for engineers and technical personnel engaged in drilling for exploratory geological works.
