This is a revised and updated edition of the highly successful first and second editions. In the intervening period the procedures used in the description of soils and rocks have continued to develop and evolve and this new edition incorporates changes in the international standards EN ISO 14688 and 14689 and those resulting in the national standard, BS 5930:2015 and the 2020 amendment thereof. Close comparison is also made with US practice in description (ASTM D2488) and classification (ASTM D2487). Significant changes in rock description are included - the reintroduction of the Approaches 1 to 5 for rock weathering; Approach 1 for description and Approaches 2 to 5 (Rock Weathering Working Party) for classification when appropriate and helpful. Also covered is the reintroduction of the 12.5 MPa boundary and the term moderately weak in rock strength description: a significant boundary in design in rock. The book continues to provide invaluable practical guidance in carrying out engineering geological logging of soil and rock samples and exposures in the field. The systematic and codified approach is laid out in detail to ensure the defined descriptors are used in a consistent format, rendering mistakes less likely and the necessary communication from field to design more successful.The procedures, techniques and tips within this book continue to serve and guide young practitioners learning their craft, but also their seniors and mentors, including responsible experts who sign off the logs and report on behalf of their company. More than ever, the need to be aware of current practices in order in order to avoid costly mistakes is paramount.

In addition, changes in definitions, naming procedures, and new terms are all included and explained.

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.

Knowledge surrounding the behavior of earth materials is important to a number of industries, including the mining and construction industries. Further research into the field of geotechnical engineering can assist in providing the tools necessary to analyze the condition and properties of the earth. Technology and Practice in Geotechnical Engineering brings together theory and practical application, thus offering a unified and thorough understanding of soil mechanics. Highlighting illustrative examples, technological applications, and theoretical and foundational concepts, this book is a crucial reference source for students, practitioners, contractors, architects, and builders interested in the functions and mechanics of sedimentary materials.

Contains virtually all current laboratory tests for soils, rocks and aggregates in one volume with references to international standards: ASTM, ISRM, BS, and AS.

This second edition of the successful Foundations on Rock presents an up-to-date practical reference book describing current engineering practice in the investigation, design and construction of foundations on rock. An extra chapter on Tension Foundations has been included. The methods set out are readily applicable to high rise buildings, bridges, dams and structures subject to uplift and turning loads. Foundations on Rock differs from the many texts and handbooks on soil foundations in that it focuses on the effect of geology on the stability and settlement of rock foundations. While the intact rock may be strong, defects in the rock such as faults, joints and cavities, and the deterioration of the rock with time, will have a significant effect on foundation performance. Methods of detecting such defects are described, and their implications for foundation design and treatment are elaborated.

This book is one of the best-known and most respected books in geotechnical engineering. In its third edition, it presents both theoretical and practical knowledge of soil mechanics in engineering. It features expanded coverage of vibration problems, mechanics of drainage, passive earth pressure, and consolidation.
