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.

Military maneuvers damage vegetation and compact and rut soils on training lands, thereby increasing the likelihood of hillslope runoff and soil erosion. Soil Freeze-Thaw (FT) processes can change the hydraulic geometry and roughness of vehicular ruts and reduce soil compaction, which often partially restores the water infiltration rate that existed before compaction. The efficiency of these FT-induced 'repairs' depends on soil water content and FT intensity. Initial tests showed that: (1) an experimental soil bin designed and constructed for rut experiments allows acceptable simulation of field soil FT, and (2) the hydraulic geometry of a rectangular rill in a fine silt soil with an initial volumetric water content of 36% changes dramatically due to rill sideslope slumping during thaw. Future experiments will compare differences in the response of natural rills and vehicular ruts to FT-induced soil failure, and investigate the effects of FT on soil erodibility and the influences of snow cover on soil erosion processes in the spring.

Two areas were monitored at the Yakima Training Center (YTC) in central Washington to measure changes in M1A2 Abrams (M1) tank-rut surface geometry, and in- and out-of-rut saturated hydraulic conductivity (Ksubfs), soil penetration resistance (SPR), and bulk density over the 1995-1996 winter. Profile meter data show that rut cross-sectional profiles smoothed significantly and that turning ruts did so more than straight ruts. Rut edges were zones of erosion and sidewall bases were zones of deposition. Ksubfs values were similar in and out of ruts formed on soil with 0-5 percent water by volume, but were lower in ruts formed on soil with about 15 percent water. Mean SPR was similar in and out of ruts from 0- to 5-cm depth, increased to 2 MPa outside ruts and 4 MPa inside ruts at 10- to 15-cm depth, and decreased by 10-38 percent outside ruts and by 39-48% inside ruts at the 30-cm depth. Soil bulk density was similar in and out of ruts from 0- to 2.5-cm depth, and below 2.5 cm it was generally higher in ruts formed on moist soil, with highest values between 10- and 20-cm depth. Conversely, density in ruts formed on dry soil was similar to out-of-rut density at all depths. This information is important for determining impacts of tank ruts on water infiltration and soil erosion, and for modifying the Revised Universal Soil Loss Equation (RUSLE) and the Water Erosion Prediction Project (WEPP) models to more accurately predict soil losses on Army training lands.

Due to the unavailability of good construction sites owing to the growth of cities and industries, the site engineers are nowadays compelled to adopt methods of forcing the weak soil to behave according to the project requirement. Written in the same context, the book focuses on the fundamental principles and practical methods of ground improvement. The design and constructional procedure of different ground improvement methods are comprehensively covered in the text. The subject-matter, divided into fourteen chapters, is organised into a simplified and logical manner to describe first the working methods and then the possible future developments. The book enables its readers to become aware of the overall methodology to be adopted in a particular case and seek possible solution to the chosen field. It is primarily intended to cater the needs of undergraduate and postgraduate students of civil engineering and geotechnical engineering. KEY FEATURES • Numerous figures, tables and mathematical equations are provided to support the topics discussed. • Several worked-out examples are provided in most of the chapters. • Objective questions, descriptive questions and references are given at the end of each chapter. • Numerical questions are given for practice in the relevant chapters. • An appendix introduces miscellaneous topics related to soil.

Twilight in the Desert reveals a Saudi oil and production industry that could soon approach a serious, irreversible decline. In this exhaustively researched book, veteran oil industry analyst Matthew Simmons draws on his three–plus decades of insider experience and more than 200 independently produced reports about Saudi petroleum resources and production operations. He uncovers a story about Saudi Arabia’s troubled oil industry, not to mention its political and societal instability, which differs sharply from the globally accepted Saudi version. It’s a story that is provocative and disturbing, based on undeniable facts, but until now never told in its entirety. Twilight in the Desert answers all readers’ questions about Saudi oil and production industries with keen examination instead of unsubstantiated posturing, and takes its place as one of the most important books of this still–young century.
