Available in PDF, EPUB and Kindle. Book excerpt: The laboratory procedure most commonly used for strength determination is the triaxial compression test. The relationship between data obtained with this test procedure and the in-situ strength of a soil under comparable deformation conditions (i.e., axially symmetric strain and same orientation of principal stresses) will be the subject of this report.

This book was released on 2012 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sample disturbance has always been a particularly challenging topic in Geotechnical Engineering exercise. The effect and importance of disturbance on stress-strain history and undrained shear strength of soft clays are well stated in the literature over the past decades. However, in practice, few qualitative methods are used even in the most complex engineering projects. Furthermore, there is not a widely accepted, quantitative method in order to assess sample disturbance and treat the lab engineering values to match the "in-situ" properties of the soil. This research consists of a systematic review of the methods available to estimate preconsolidation pressure and sample quality. It focuses on multiple disturbance-simulation triaxial tests on resedimented San Francisco Bay Mud (RSFBM) specimens. The effect of different ISA disturbance amplitudes (Baligh et al. 1987) on the compression curve and the preconsolidation pressure is quantified. After every disturbance simulation circle, the specimens are reconsolidated using SHANSEP technique, well into the Virgin Compression Line (VCL), to erase all the previous effects of disturbance. Then, every recompression curve is treated as an initial compression phase but, of known disturbance. A series of tests are performed in Normally Consolidated (NC) and Overconsolidated (OC) specimens over a wide range of stresses. The effect of disturbance on an element outside the centerline of the sampling tube is simulated. A new method to quantify disturbance based on a modified recompression and compression indices ratio is proposed. Results indicate that for medium sensitivity soils, disturbance does not have a significant effect on preconsolidation pressure. However, increasing disturbance decreases significantly the researcher's capability to define with accuracy the preconsolidation pressure value. The calculated value can be overestimated as well as underestimated. Santagata and Germaine's (1994) conceptual model is verified experimentally. The model characterizes the loss of effective stresses and the change of VCL slope as the two most important outputs of disturbance that play a key role in the value of preconsolidation pressure. Results also indicate that the effects of disturbance are much less apparent when the OCR increases and that accounting for swelling leads to an overestimation of the preconsolidation pressure.

Available in PDF, EPUB and Kindle. Book excerpt: This book gathers the most recent scientific research on the geological, geotechnical and geophysical aspects of slope failure in sensitive clays. Gathering contributions by international experts, it focuses on understanding the complete and practical spectrum of challenges presented by landslides in such complex materials. Based on sound and validated research results, the book also presents several recommendations that could be implemented in the guidelines or code-of-practice. These recommendations cover topics including the characterization and behavior of sensitive clays; the pre-failure, failure and post-failure stages of sensitive clays; mapping and identification methods; climate change; hazard assessment; and risk management. Sensitive clays are known for their potential for causing large landslides, which pose a serious risk to human lives, infrastructure, and surrounding ecosystems within their reach. This has been demonstrated by the recent catastrophic landslides in e.g. Sørum (2016), Skjeggestad (2015), Statland (2014), Byneset (2012), St-Jude (2010), Lyngen (2010) and Kattmarka (2009). The 2015 collapse of the Skjeggestad Bridge in Norway – which was due to a landslide in sensitive clay – alone costs millions of dollars in repairs. Recently, efforts are being made to increase society’s ability to cope with such landslide hazards. Geoscientists are now expected to provide input to the agencies responsible for landslide-risk preparedness. In other words, geoscientists’ role is not only to act as technologists to establish new theories, but also to go the extra mile to implement them in practice, so as to find meaningful solutions to geotechnical problems.

Available in PDF, EPUB and Kindle. Book excerpt: In November 2015, Buenos Aires, Argentina became the location of several important events for geo-professionals, with the simultaneous holding of the 6th International Symposium on Deformation Characteristics of Geomaterials, the 15th Pan-American Conference on Soil Mechanics and Geotechnical Engineering (XV PCSMGE), the 8th South American Congress on Rock Mechanics (SCRM), as well as the 22nd Argentinean Congress of Geotechnical Engineering (CAMSIGXXII). This synergy provided a unique opportunity to exchange ideas and discuss current and future practices in the areas of soil mechanics and rock mechanics, and their applications in civil, energy, environmental, and mining engineering. This book presents the proceedings of the 6th International Symposium on Deformation Characteristics of Geomaterials. As well as 118 articles selected for publication after peer review, it includes 7 lectures delivered by invited keynote speakers and the Third Bishop Lecture, delivered by Professor Herve Di Benedetto of the University of Lyon, France, who presented a reference work on the advanced testing and modeling of bituminous bounded and unbounded granular materials. The conference brought together practitioners, researchers and educators from around the world engaged in the understanding of the deformation properties of geo-materials before failure, and the small strain parameters as fundamental characteristics of geo-materials. The main topics covered by the symposium include experimental investigations from very small strains to beyond failure, including multi-physical approach; HTC M coupling behavior, characterization and modeling of various geo-materials and interfaces; and practical prediction and interpretation of ground responses: field observation and case histories.

Download or read book Foundation Engineering Handbook written by Hsai-Yang Fang and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 935 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than ten years have passed since the first edition was published. During that period there have been a substantial number of changes in geotechnical engineering, especially in the applications of foundation engineering. As the world population increases, more land is needed and many soil deposits previously deemed unsuitable for residential housing or other construction projects are now being used. Such areas include problematic soil regions, mining subsidence areas, and sanitary landfills. To overcome the problems associated with these natural or man-made soil deposits, new and improved methods of analysis, design, and implementation are needed in foundation construction. As society develops and living standards rise, tall buildings, transportation facilities, and industrial complexes are increasingly being built. Because of the heavy design loads and the complicated environments, the traditional design concepts, construction materials, methods, and equipment also need improvement. Further, recent energy and material shortages have caused additional burdens on the engineering profession and brought about the need to seek alternative or cost-saving methods for foundation design and construction.
