Available in PDF, EPUB and Kindle. Book excerpt: The results of consolidated-undrained direct-simple shear tests are presented on seven normally consolidated clays of widely varying composition and plasticity. The effect of overconsolidation ratio is studied with six of these clays. The tests were performed with the Geonor device, which uses a 8.0 cm dia. sample enclosed in a wire-reinforced rubber membrane. The vertical load is varied to maintain constant volume during undrained shear. Consolidated undrained direct-simple shear tests are easier to perform than K sub o - consolidated triaxial tests with pore pressure measurements. The test also yields data during consolidation similar to that obtained from conventional oedometer tests. (Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: Several series of consolidated undrained direct translatory shear (DTS) and direct simple shear (DSS) tests have been performed on two sensitive clays of eastern Canada. Before shearing, the specimens were consolidated to pressures varying between 20 and 350 kPa. The investigation was performed with the aim of determining both the anisotropic nature and the effect of the consolidation pressure level on the response of the tested clays. To study the anisotropic nature of the sensitive clays, the specimens were cut at various inclination angles with respect to the in-situ horizontal plane, consolidated to predetermined normal stress levels, thus altering the fabric, and then sheared under undrained conditions. The range of the normal stress levels used was such as to be able to investigate the response of the soil from very high overconsolidation ratios to normally consolidated or destructured states. The results show that for consolidation pressures less than the preconsolidation pressures of the inclined specimens, the undrained shear strengths are anisotropic. In this case, the specimens that are sheared along the horizontal in-situ direction show the lowest strength, while those that are sheared along the vertical in-situ direction have the highest strength. However, for the specimens that are consolidated under pressures in excess of the preconsolidation pressures, the undrained shear strengths are found to be independent of shearing direction.

Download or read book Effect of Volume Change in Undrained Direct Simple Shear Tests written by Helene Alexandra Amundsen and published by . This book was released on 2019 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to perform constant-volume (equivalent to undrained) Direct Simple Shear (DSS) tests using either a wire-reinforced membrane or stacked rings as the zero lateral strain confinement system, the height (and thereby volume) of the test specimen must be maintained at a constant during shear. The change in vertical stress while maintaining constant specimen height during shear is equivalent to the excess pore pressure that would have developed in a truly undrained DSS test. Depending on the control capabilities of active height-control DSS devices and the stiffness of locked (passive) height-control DSS devices, the specimen height may not be perfectly constant throughout shear in some cases. This technical note presents the results of monotonic constant-volume DSS tests where the specimen height was intentionally varied during shear to demonstrate the effect on measured shear stress and vertical effective stress. Changing the test specimen height by 0.05 % (the maximum specified by ASTM D6528, Standard Test Method for Consolidated Undrained Direct Simple Shear Testing of Fine Grain Soils) affected the test results. The percentage deviations in the measured test results are greater for stiffer soil specimens, about 2 % for soft normally consolidated clay and more than 20 % for dense sand at failure.

Download or read book Cone Penetration Testing 2022 written by Guido Gottardi and published by CRC Press. This book was released on 2022-06-24 with total page 2767 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the 5th International Symposium on Cone Penetration Testing (CPT’22), held in Bologna, Italy, 8-10 June 2022. More than 500 authors - academics, researchers, practitioners and manufacturers – contributed to the peer-reviewed papers included in this book, which includes three keynote lectures, four invited lectures and 169 technical papers. The contributions provide a full picture of the current knowledge and major trends in CPT research and development, with respect to innovations in instrumentation, latest advances in data interpretation, and emerging fields of CPT application. The paper topics encompass three well-established topic categories typically addressed in CPT events: - Equipment and Procedures - Data Interpretation - Applications. Emphasis is placed on the use of statistical approaches and innovative numerical strategies for CPT data interpretation, liquefaction studies, application of CPT to offshore engineering, comparative studies between CPT and other in-situ tests. Cone Penetration Testing 2022 contains a wealth of information that could be useful for researchers, practitioners and all those working in the broad and dynamic field of cone penetration testing.

Available in PDF, EPUB and Kindle. Book excerpt: The work of geotechnical engineers contributes to the creation of safe, economic and pleasant spaces to live, work and relax all over the world. Advances are constantly being made, and the expertise of the profession becomes ever more important with the increased pressure on space and resources. This book presents the proceedings of the 15th Pan-American Conference on Soil Mechanics and Geotechnical Engineering (XV PCSMGE), held in Buenos Aires, Argentina, in November 2015. This conference, held every four years, is an important opportunity for international experts, researchers, academics, professionals and geo-engineering companies to meet and exchange ideas and research findings in the areas of soil mechanics, rock mechanics, and their applications in civil, mining and environmental engineering. The articles are divided into nine sections: transportation geotechnics; in-situ testing; geo-engineering for energy and sustainability; numerical modeling in geotechnics; foundations and ground improvement; unsaturated soil behavior; embankments, dams and tailings; excavations and tunnels; and geo-risks, and cover a wide spectrum of issues from fundamentals to applications in geotechnics. This book will undoubtedly represent an essential reference for academics, researchers and practitioners in the field of soil mechanics and geotechnical engineering. In this proceedings, approximately 65% of the contributions are in English, and 35% of the contributions are in Spanish or Portuguese.

Download or read book Fundamentals of Foundation Engineering written by Chang-Yu Ou and published by CRC Press. This book was released on 2023-09-18 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to introduce the principle and design of various foundations, covering shallow foundations, mat foundations, earth retaining structures, excavations, pile foundations, and slope stability. Since the analysis and design of a foundation are based on the soil properties under short-term (undrained) or long-term (drained) conditions, the assessment of soil properties from the geotechnical site investigation and the concept of drained or undrained soil properties are discussed in the first two chapters. Foundation elements transfer various load combinations from the superstructure to the underlying soils or rocks. The load transfer mechanisms, vertical stress or earth pressure distributions, and failure modes of each foundation type are clearly explained in this book. After understanding the soil responses subjected to the loadings from the foundation, the design methods, required factors of safety, and improvement measures for each foundation type are elaborated. This book presents both theoretical explication and practical applications for readers to easily comprehend the theoretical background, design methods, and practical applications and considerations. Each chapter provides relevant exercise examples and a problem set for self-practice. The analysis methods introduced in the book can be applied in actual analysis and design as they contain the most up-to-date knowledge of foundation design. This book is suitable for teachers and students to use in foundation engineering courses and engineers who are engaged in foundation design to create a technically sound, construction-feasible, and economical design of the foundation system.
