Available in PDF, EPUB and Kindle. Book excerpt: A new hybrid resonant column/torsional shear apparatus has been developed, which permits the determination of dynamic soil properties on a single solid or hollow cylinder specimen over the entire range of shear strain amplitudes of engineering interest, that is, from 10-4 to 10%. The main characteristics of both the resonant column and torsional shear tests are presented with emphasis on those factors that influenced the design of the new apparatus. The new apparatus is described in detail, and representative test results to demonstrate its capabilities are presented.

Available in PDF, EPUB and Kindle. Book excerpt: Torsional resonant column tests were performed on Monterey No. 0 sand of 60% relative density under confining pressures ranging from 10 to 300 kPa to evaluate the dynamic properties of the sand. Both solid and hollow cylindrical specimens were used in testing, and shear moduli and damping ratios were determined for cyclic shear strain amplitudes from 10-4 to 5 × 10-2%. The test results indicated that the type of specimen, that is, solid or hollow cylinder, had no significant effect on the calculated shear moduli and damping ratios, except that at very low strain amplitudes (?

Available in PDF, EPUB and Kindle. Book excerpt: In recent decades the development of unsaturated soil mechanics has been remarkable, resulting in momentous advances in fundamental knowledge, testing techniques, computational procedures, prediction methodologies and geotechnical practice. The advances have spanned the full spectrum of theory and practice. In addition, unsaturated materials exhibiting complex behaviour such as residual soils, swelling soils, compacted soils, collapsing soils, tropical soils and solid wastes have been integrated in a common understanding of shared behaviour features. It is also noteworthy that unsaturated soil mechanics has proved surprisingly fruitful in expanding to other neighbouring areas such as swelling rocks, rockfill mechanics, and freezing soils. As a consequence, geotechnical engineering involving unsaturated soils can be now approached from a more rational and systematic perspective leading towards an improved and more effective practice. Unsaturated Soils contains the papers presented at the 5th International Conference on Unsaturated Soil (Barcelona, Spain, 6-8 September 2010). They report significant advances in the areas of unsaturated soil behaviour, testing techniques, constitutive and numerical modelling and applications. The areas of application include soil-atmosphere interaction, foundations, slopes, embankments, pavements, geoenviromental problems and emerging topics. They are complemented by three keynote lectures and three general reports covering general issues of modelling, testing and applications. Unsaturated Soils is a comprehensive record of the state-of-the art in unsaturated soil mechanics and a sound basis for further progress in the future. The two volumes will serve as an essential reference for academics, researchers and practitioners interested in unsaturated soils.

Download or read book Soft Soil Engineering written by Dave H. Chan and published by CRC Press. This book was released on 2006-09-28 with total page 808 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soft soils present particular challenges to engineers and an understanding of the specific characteristics of these soils is indispensable. Laboratory techniques such as numerical modelling, theoretical analysis and constitutive modelling give new insights into soft soil material behaviour, while large-scale testing in the field provides important information in areas such as slope stability and soft soil improvements. This collection of papers from the Fourth International Conference on Soft Soil Engineering, Vancouver, 2006, presents an international appraisal of current research and new advances in engineering practices, illustrating the theory with relevant case studies. Geotechnical professionals, engineers, academics and researchers working in the areas of soft ground engineering and soft soil engineering will find this a valuable book.

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 Effects of Oversized Particles on the Dynamic Properties of Sand Specimens Evaluated by Resonant Column Testing written by Boonam Shin and published by . This book was released on 2014 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was motivated by the fact that many times intact specimens with a number of oversized particles are dynamically tested in the laboratory and the impact of the particles on the dynamic properties is unknown. The effects of oversized particles represented by gravel particles on the shear modulus (G) and material damping ratio (D) of a uniform sand were evaluated in the linear ([gamma] ≤ 0.001%) and nonlinear ([gamma] > 0.001%) ranges of shear strain with combined resonant column and torsional shear (RCTS) equipment. The sand used in this investigation is a uniform sand as a reference, well-characterized material on the dynamic properties. Sand-gravel specimens were constructed using the undercompaction method. A variety of rounded gravel particles was used in building the specimens. Dynamic tests on the sand-gravel specimens were performed, and the tests results are presented. Among the findings of this investigation are that, compared to uniform sand: (1) oversized gravel particles symmetrically located along the longitudinal axis in uniform sand generally decreased slightly the small-strain shear modulus (Gm̳a̳x̳), (2) oversized gravel particles asymmetrically located away from the longitudinal axis of rotation resulted in slight increases in Gm̳a̳x̳ and the small-strain material damping ratio (Dm̳i̳n̳), (3) the G - log [gamma] relationships of sand-gravel specimens with asymmetrically located gravel particles are generally above those with gravel particles symmetrically located along the longitudinal axis, and (4) the G/Gm̳a̳x̳ - log [gamma] relationships of all specimens were reasonably close for the nonlinear ranges covered in these tests ([gamma] 0.05 % and G/Gm̳a̳x̳ 0.6). As long as the oversized particles were near the axis of rotation, the particles had little effect on the dynamic properties (Gm̳a̳x̳, Dm̳i̳n̳ and G - log [gamma] relationships) regardless of sizes and numbers of particles. However, once the oversized particles were located away from the axis of rotation and closer to the perimeter of the specimen, the oversized particles influenced the dynamic properties. Finally, the additions of oversized particles located both symmetrically and asymmetrically in the uniform sand specimens have little impact on the nonlinear dynamic properties (G/Gm̳a̳x̳ - log [gamma] and D - log [gamma] relationships) which compared well with uniform sand.

This book was released on 2015 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of the dynamic properties of two specific kinds of granular soils is performed using torsional resonant column testing. The sandy soils are: (1) liquefiable sand from Christchurch, New Zealand, and (2) calcareous sand from Puerto Rico. The effects of isotropic effective confining pressure, shear strain amplitude, void ratio, and total unit weight on the small-strain and nonlinear dynamic properties of both types of sand are presented and discussed. Empirical models from previous studies are examined to determine how well the models fit the test results.
