Introduction

What is the book about?

The book Foundations and Earth Retaining Structures is a textbook written primarily for an undergraduate course in foundation analysis and design. It covers the basic concepts and fundamental principles that are necessary to understand the background of the methods employed in foundation design. It also informs students on the values and limitations of popular methods of analyses in foundation engineering. Finally, it provides a framework for students to carry out simple foundation design and appreciate the design process.

The book is divided into four main parts: review of basic soil mechanics, shallow foundations, deep foundations, and earth retaining structures. Each part consists of several chapters that explain the theory, methods, examples, and problems related to each topic. The book also includes appendices that provide useful information on soil properties, units, symbols, equations, charts, tables, etc.

The book is written in a clear and concise manner, with an emphasis on fundamentals rather than procedures. However, practical procedures, where appropriate, are included to allow students to transit into "office" design. The topics are sequenced so as not to rush the students into design but to build a solid foundation in the fundamentals so that they could understand the implications of the assumptions in the design.

Who is the author?

The author of the book is Muni Budhu, a professor of civil engineering and engineering mechanics at The University of Arizona. He has over 30 years of teaching experience in geotechnical engineering at various universities around the world. He has also been involved in research and consulting projects on topics such as soil-structure interaction, slope stability, liquefaction, ground improvement, geosynthetics, etc.

Professor Budhu has published several books and papers on geotechnical engineering, including Soil Mechanics Fundamentals, Soil Mechanics Laboratory Manual, Soil Mechanics: A Practical Approach, etc. He has also received several awards for his teaching and research excellence, such as the ASCE Excellence in Civil Engineering Education Award, the ASEE Outstanding Teaching Award, the NSF CAREER Award, etc.

Why is it important for civil engineers?

The book Foundations and Earth Retaining Structures is important for civil engineers because it provides them with the essential knowledge and skills to design and construct safe and economical foundations and earth retaining structures for various types of civil engineering projects. Foundations and earth retaining structures are critical components of any civil engineering structure, such as buildings, bridges, dams, tunnels, highways, etc. They support the loads from the superstructure and transfer them to the underlying soil or rock. They also prevent the lateral movement or collapse of the soil due to external forces or changes in groundwater conditions.

Civil engineers need to understand the behavior and properties of soils and rocks, the methods of analysis and design of foundations and earth retaining structures, the factors that affect their performance and reliability, and the techniques of construction and quality control. The book Foundations and Earth Retaining Structures provides civil engineers with a comprehensive and up-to-date source of information on these topics. It also helps them to develop their critical thinking and problem-solving abilities, as well as their creativity and innovation skills.

Review of Basic Soil Mechanics

The first part of the book reviews the basic concepts and principles of soil mechanics that are relevant to foundation engineering. It consists of four chapters that cover the following topics:

Soil properties and classification

This chapter introduces the origin, formation, and composition of soils, as well as their physical, mechanical, and hydraulic properties. It also explains the methods of soil identification and classification based on grain size, plasticity, organic content, etc. It also discusses the concept of soil compaction and its effects on soil properties.

Stress and strain in soils

This chapter explains the concepts of stress and strain in soils, as well as their measurement methods. It also describes the stress-strain relationships for different types of soils under various loading conditions. It also introduces the concepts of elasticity, plasticity, failure criteria, and strength parameters for soils.

Effective stress principle

This chapter presents the effective stress principle, which is one of the most fundamental concepts in soil mechanics. It states that the total stress acting on a soil element is equal to the sum of the effective stress (due to intergranular contact) and the porewater pressure (due to water in voids). It also explains how to calculate the effective stress and porewater pressure at any point in a soil mass under various loading conditions.

Consolidation and settlement

This chapter discusses the phenomenon of consolidation, which is the gradual reduction in volume of a saturated clayey soil due to drainage of excess porewater pressure under an applied load. It also explains how to estimate the magnitude and rate of consolidation settlement using laboratory tests (e.g., oedometer test) or field measurements (e.g., piezometers). It also introduces the concepts of immediate settlement (due to elastic deformation) and secondary compression (due to creep).

Shallow Foundations

The second part of the book deals with shallow foundations, which are foundations that are placed near or at the ground surface. It consists of four chapters that cover the following topics:

Types and applications of shallow foundations

This chapter describes the different types of shallow foundations, such as strip footings, isolated footings, combined footings, mat foundations, etc. It also explains their applications for various types of structures, such as buildings, bridges, tanks, etc. It also discusses some factors that influence the selection of shallow foundations, such as site conditions, loading characteristics, economy, etc.

Bearing capacity and failure modes

This chapter explains the concept of bearing capacity, which is the maximum load per unit area that a foundation can support without causing excessive settlement or failure. It also describes the different modes of failure that can occur in shallow foundations, such as general shear failure, local shear failure, punching shear failure, etc. It also presents some methods of analysis for estimating the ultimate bearing capacity of shallow foundations based on limit equilibrium or limit analysis principles.

Settlement analysis and design criteria

This chapter explains how to estimate the settlement of shallow foundations due to various sources of deformation, such as immediate settlement (elastic), consolidation settlement (time-dependent), secondary compression (creep), etc. It also presents some methods of analysis for calculating the settlement based on empirical correlations or theoretical solutions. It also discusses some design criteria for limiting the allowable settlement based on serviceability or safety considerations. 71b2f0854b
