Description

This module is an introduction to Soil Mechanics & Geology, assuming no prior knowledge of the subject. The student starts with the formation and origin of rocks and the processes which result in the formation of soil before learning how these processes influence soil behaviour due to external loading or the flow of fluid through the soil.

Learning Outcomes

On completion of this module the learner will/should be able to;

Identify and classify soils and rocks and calculate their phase relations. Describe how rock and rock structures are formed and weathered.

Compute coefficients of permeability from standard laboratory tests and compute critical hydraulic gradients.

Calculate total stress, effective stress and porewater pressure and evaluate the shear strength parameters of the soil in drained and undrained conditions. Calculate lateral earth pressures.

Estimate one-dimensional settlements in soils.

Use standard laboratory equipment and perform as a team member in the execution, compilation, analysis and interpretation of laboratory experiments

Compile and report, in both written and oral form, using word and excel, the results and conclusions of laboratory work

Teaching and Learning Strategies

ISBN 9780470673393 ISBN-13 0470673397

The 9th edition maintains the content on all soil mechanics subject areas - groundwater flow, soil physical properties, stresses, shear strength, consolidation and settlement, slope stability, retaining walls, shallow and deep foundations, highways, site investigation - but has been expanded to include a detailed explanation of how to use Eurocode 7 for geotechnical design. The key change in this new edition is the expansion of the content covering Geotechnical Design to Eurocode 7. Redundant material relating to the now defunct British Standards - no longer referred to in degree teaching - has been removed. Building on the success of the earlier editions, this 9th edition of Smith?s Elements of Soil Mechanics brings additional material on geotechnical design to Eurocode 7 in an understandable format. Many worked examples are included to illustrate the processes for performing design to this European standard. Significant updates throughout the book have been made to reflect other developments in procedures and practices in the construction and site investigation industries. More worked examples and many new figures have been provided throughout. The illustrations have been improved and the new design and layout of the pages give a lift. unique content to illustrate the use of Eurocode 7 with essential guidance on how to use the now fully published code clear content and well-organised structure takes complicated theories and processes and presents them in easy-to-understand formats book's website offers examples and downloads to further understanding of the use of Eurocode 7 www.wiley.com/go/smith/soil

2009-04-21 Foundations of Engineering Geology, Third Edition CRC Press
ISBN 0415469600 ISBN-13 9780415469609

Now in full colour, the third edition of this well established book provides a readable and highly illustrated overview of the aspects of geology that are most significant to civil engineers. Sections in the book include those devoted to the main rock types, weathering, ground investigation, rock mass strength, failures of old mines, subsidence on peats and clays, sinkholes on limestone and chalk, water in landslides, slope stabilization and understanding ground conditions. The roles of both natural and man-induced processes are assessed, and this understanding is developed into an appreciation of the geological environments potentially hazardous to civil engineering and construction projects. For each style of difficult ground, available techniques of site investigation and remediation are reviewed and evaluated. Each topic is presented as a double page spread with a careful mix of text and diagrams, with tabulated reference material on parameters such as bearing strength of soils and rocks. This new edition has been comprehensively updated and covers the entire spectrum of topics of interest for both students and practitioners in the field of civil engineering.

This book explains the process of ground formation what it is made of and how it behaves as an engineering material. This enables the civil engineer to work from a few first principles to determine if the ground is an asset or a hazard. It focuses on the tectonic plate mechanisms that give rise to the geology of our planet and describes the way these create hazards such as volcanic eruptions, earthquakes and tsunamis. The authors state that groundwater can be both a resource and a hazard and through this book they provide an overview of the origins of geomaterials."

ISBN 0750680776 ISBN-13 9780750680776

Every engineering structure, whether it's a building, bridge or road, is affected by the ground on which it is built. Geology is of fundamental importance when deciding on the location and design of all engineering works, and it is essential that engineers have a basic knowledge of the subject. Engineering Geology introduces the fundamentals of the discipline and ensures that engineers have a clear understanding of the processes at work, and how they will impact on what is to be built. Core areas such as stratigraphy, rock types, structures and geological processes are explained, and put in context. The basics of soil mechanics and the links between groundwater conditions and underlying geology are introduced. As well as the theoretical knowledge necessary, Professor Bell introduces the techniques that engineers will need to learn about and understand the geological conditions in which they intend to build. Site investigation techniques are detailed, and the risks and risk avoidance methods for dealing with different conditions are explained. * Accessible introduction to geology for engineers * Key points illustrated with diagrams and photographs * Teaches the impact of geology on the planning and design of structures

Instead of fixating on formulae, Soil Mechanics: Concepts and Applications, Third Edition focuses on the fundamentals. This book describes the mechanical behaviour of soils as it relates to the practice of geotechnical engineering. It covers both principles and design, avoids complex mathematics whenever possible, and uses simple methods and ideas to build a framework to support and accommodate more complex problems and analysis. The third edition includes new material on site investigation, stress-dilatancy, cyclic loading, non-linear soil behaviour, unsaturated soils, pile stabilization of slopes, soil/wall stiffness and shallow foundations. Other key features of the Third Edition: Makes extensive reference to real case studies to illustrate the concepts described Focuses on modern soil mechanics principles, informed by relevant research Presents more than 60 worked examples Provides learning objectives, key points, and self-assessment and learning questions for each chapter Includes an accompanying solutions manual for lecturers This book serves as a resource for undergraduates in civil engineering and as a reference for practising geotechnical engineers.
