Download or read book On the Sensitivity of Soft Clay Obtained by the Field Vane Test written by Yan-Bin Gao and published by . This book was released on 2015 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field vane test (FVT) is used more widely today in traditional site investigations to investigate the sensitivity of soft clay and even likely to replace the unconfined compression test (UCT). In this paper, the strengths and sensitivities of Shanghai soft clays obtained by an FVT and a UCT from a traditional site investigation and that obtained by the laboratory vane test (LVT) and the UCT on block samples were compared in detail. It was found that the FVT obtains higher strengths but lower sensitivity. This phenomenon was also observed in other soft clays. The unreliability of sensitivity determination by the FVT seems to increase with the liquid index and sensitivity of soil. The vane remolding method used in the FVT was found to be the major factor that causes these problems and cannot remold soil completely using the recommended number of vane rotations.
Download or read book Correlations of Soil and Rock Properties in Geotechnical Engineering written by Jay Ameratunga and published by Springer. This book was released on 2015-12-11 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a one-stop reference to the empirical correlations used extensively in geotechnical engineering. Empirical correlations play a key role in geotechnical engineering designs and analysis. Laboratory and in situ testing of soils can add significant cost to a civil engineering project. By using appropriate empirical correlations, it is possible to derive many design parameters, thus limiting our reliance on these soil tests. The authors have decades of experience in geotechnical engineering, as professional engineers or researchers. The objective of this book is to present a critical evaluation of a wide range of empirical correlations reported in the literature, along with typical values of soil parameters, in the light of their experience and knowledge. This book will be a one-stop-shop for the practising professionals, geotechnical researchers and academics looking for specific correlations for estimating certain geotechnical parameters. The empirical correlations in the forms of equations and charts and typical values are collated from extensive literature review, and from the authors' database.
Download or read book Ground Improvement written by Professor Jian Chu and published by Elsevier. This book was released on 2005-11-07 with total page 1137 pages. Available in PDF, EPUB and Kindle. Book excerpt: - The first book of its kind, providing over thirty real-life case studies of ground improvement projects selected by the worlds top experts in ground improvement from around the globe. - Volume 3 of the highly regarded Elsevier Geo-engineering book series coordinated by the Series Editor: Professor John A Hudson FREng. - An extremely reader friendly chapter format. - Discusses wider economical and environmental issues facing scientists in the ground improvement.Ground improvement has been both a science and art, with significant developments observed through ancient history. From the use of straw as blended infill with soils for additional strength during the ancient Roman civilizations, and the use of elephants for compaction of earth dams during the early Asian civilizations, the concepts of reinforced earth with geosynthetics, use of electrokinetics and thermal modifications of soils have come a long way. The use of large and stiff stone columns and subsequent sand drains in the past has now been replaced by quicker to install and more effective prefabricated vertical drains, which have also eliminated the need for more expensive soil improvement methods.The early selection and application of the most appropriate ground improvement techniques can improve considerably not only the design and performance of foundations and earth structures, including embankments, cut slopes, roads, railways and tailings dams, but also result in their cost-effectiveness. Ground improvement works have become increasingly challenging when more and more problematic soils and marginal land have to be utilized for infrastructure development.This edited compilation contains a collection of Chapters from invited experts in various areas of ground improvement, who have illustrated the basic concepts and the applications of different ground improvement techniques using real projects that they have been involved in. The case histories from many countries ranging from Asia, America, Australia and Europe are addressed.
Download or read book Landslides in Sensitive Clays written by Vikas Thakur and published by Springer. This book was released on 2017-05-23 with total page 593 pages. 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.

Download or read book In Situ Testing Methods in Geotechnical Engineering written by Alan J. Lutenegger and published by CRC Press. This book was released on 2021-05-03 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Situ Testing Methods in Geotechnical Engineering covers the field of applied geotechnical engineering related to the use of in situ testing of soils to determine soil properties and parameters for geotechnical design. It provides an overview of the practical aspects of the most routine and common test methods, as well as test methods that engineers may wish to include on specific projects. It is suited for a graduate-level course on field testing of soils and will also aid practicing engineers. Test procedures for determining in situ lateral stress, strength, and stiffness properties of soils are examined, as is the determination of stress history and rate of consolidation. Readers will be introduced to various approaches to geotechnical design of shallow and deep foundations using in situ tests. Importantly, the text discusses the potential advantages and disadvantages of using in situ tests.

Download or read book Factors Affecting the Measurements and Interpretation of the Vane Strength in Soft Sensitive Clays written by A. Leblanc and published by . This book was released on 1988 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vane tests have been carried out in the field and in the laboratory to investigate some factors affecting the measurements and interpretation of the test, specially the disturbance caused by the insertion of the vane into the clay and the time and shear velocity effects on the strength. Strength rotation curves and failure diagrams have been investigated in the laboratory. The results have shown that the insertion of the vane produces disturbance and generates pore pressure so that the vane strength measured is reduced while time effect leads to an increase in shear strength. Study of the failure diagram shows that the actual shear surface is larger than the cylindrical surface defined by the diameter of the blades.
