Download or read book Instabilities in alpine permafrost: strength and stiffness in a warming regime written by Yuko Yamamoto and published by vdf Hochschulverlag AG. This book was released on 2014-08-20 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alpine permafrost exists at high altitude at lower latitudes, such as in the Swiss Alps. Accelerating climate change, including rising mean annual air temperature and extreme rainfall conditions in alpine regions induces permafrost degradation. The warming of permafrost causes accelerated creep of rock glaciers, due to increased unfrozen water content and higher deformability of the ice phase. Recently, the development of deepening depressions has been observed in several rock glaciers in Switzerland, and the changes in land surface characteristics and drainage systems may initiate slope instabilities in rock glaciers. The main aim of this thesis is to characterise the strength and stiffness of alpine frozen soil in rock glaciers. To this end, the geotechnical response, such as creep and failure of frozen soil was investigated through a triaxial stress path testing programme with novel measurement systems for detecting acoustic emissions and measuring volumetric change. In addition, the resistance to crack initiation and propagation was investigated through a beam bending test programme on rectangular artificially frozen soil specimens, using the acoustic emission measurement system. The evaluation of laboratory tests on artificially frozen soil specimens implied that the development of deep depressions in rock glaciers occurs through differential creep and thermal degradation, and that the rate of deformation has the potential to lead to instabilities in rock glaciers. A comparison of the simulation results with the experimental data demonstrated that the semi-coupled model was successful in simulating the most important aspects of the temperature-dependent stress-strain relationship for the frozen soil behaviour that was measured at the element scale. This thesis contributes to an understanding of the variations in geotechnical response of alpine permafrost, by investigating the behaviour of artificially frozen soil specimens experimentally and numerically with time and temperature under specific stress paths. However, further investigations are necessary to assess the long-term stability of rock glaciers affected by climate change.

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.

This book was released on 2006-02-23 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has become increasingly important, particularly in an urban environment, to predict soil behaviour and to confine the settlement or deformation of buildings adjacent to construction sites. One important factor is the choice of construction procedure for the installation of piles, sheet pile walls, anchors or for soil improvement techniques, ground freezing and tunnelling methods. The modelling of construction processes, which are frequently associated with large deformations of the soil and with strong changes in the structure of the soil around the construction plant, in the case of, for example, a drill, a bit, a vibrator, or an excavation tool, requires sophisticated and new methods in numerical modelling. Often the simulation of the construction procedure is neglected in the calculations. Such methods are described and discussed in this book, as are examples of the methods applied to geotechnical practice, field and laboratory testing as well as case studies. This volume provides a valuable source of reference for scientists in geotechnical engineering and numerical modelling, geotechnical engineers, post graduate students, construction companies and consultants, manufacturers of geotechnical construction plants and software suppliers and developers of geotechnical construction methods.

Download or read book Geomorphological Processes written by E. Derbyshire and published by Routledge. This book was released on 2019-03-13 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book originated from a proposal by one author (J. R. H.) who was subsequently joined by a second (E. D.) and then by a third (K. J. G.). It has taken longer to produce than we expected because of the complications imposed by the distances which the authors have succeeded in putting between themselves during the past three years. The basic objective was to produce a short book which would introduce geomorphological processes to students in the first or second year of their higher education courses. We believed that there was a need for such a book reviewing a range of geomorphological processes which would offer a prelude to the symphonies which are available in books devoted to specific processes and their effects, many of which are sign posted in the lists of further reading at the end of each chapter. We are aware that the range of suitable preludes is wide, but we have endeavoured to compose one which expresses at least some of the recent achieve-ments in the study of geomorphological processes. Emphasis is placed on the nature of processes and upon their controls but the effects of processes in creating landforms are not reviewed in any detail. In addition to the selected references at the end of each chapter, we have collected a bibliography of works cited at the end of the book but this is not intended to be as exhaustive as the references collated in more advanced works.

Book excerpt: This collection of papers by internationally known scientists in the field of geocryology was originally presented as a series of lectures at the University of British Columbia in 1980-1 in honour of J. Ross MacKay. Together they illustrate the central dilemma in a science where fieldwork must be undertaken in the harsh periglacial environment and where, consequently, it is difficult to test theory rigorously. The papers provide a valuable overview of the current status of international research in a wide area of the field -- permafrost, patterned ground, and cold climate phenomena and processes. The treatment varies from anecdotal, historical, and descriptive to mathematical.
