Available in PDF, EPUB and Kindle. Book excerpt: The cause and the nature of anisotropy in a cohesive soil was investigated by direct shear and triaxial compression tests. Samples formed under hydrostatic stress showed isotropic shear strength and pore pressure behavior as well as the lack of bias in soil fabric. When the samples from the same clay were molded under one-dimensional consolidation stress, the pore pressure was observed to be isotropic, but the effective stress shear strength was not. Also, these samples had oriented soil structure. The anisotropic strength resulted from the sample stress history and not from the stresses existing prior to shearing. The ratio between the pore pressure at failure and the mean consolidation pressure during remolding, as well as the inclination of the failure plane to the specimen axis, were observed to be essentially constant for all specimens.

Available in PDF, EPUB and Kindle. Book excerpt: The cause and the nature of anisotropy in a cohesive soil was investigated by direct shear and triaxial compression tests. Laboratory techniques and procedures used to prepare isotropic clay samples are given where consolidation was accomplished under hydrostatic pressure. Direct shear tests were performed on these specimens trimmed at different inclinations to the physical horizontal from the block samples. The ratio of undrained shear strengths in any direction to shear strength in the vertical direction was found to be equal to one, proving isotropy existed. Similar tests were performed on specimens trimmed from the same clay consolidated one-dimensionally. Results from these tests showed the shear strength ratio to be maximum for specimens trimmed at 90° to the horizontal plane. In this case, the aniso- tropic characteristics were directly attributed to the sample stress history. These samples indicated preferred particle orientation. Undrained triaxial compression tests were performed on both hydrostatic and one-dimensionally consolidated samples. Triaxial test results confirmed the results of the direct shear tests and more accurately defined the stress/strength parameters. The angle between the failure plane and the test specimens axis was essentially constant and the ratio between pore water pressure at failure and the mean consolidation stress remained a constant. For each maximum consolidation stress, pore pressure was isotropic, but in all cases was higher for hydrostatically prepared samples. The hydrostatic method of preparing isotropic test specimens was effective and produced reliable results.

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.
