What is Foundation Engineering?

Foundation engineering is a branch of civil engineering that deals with the design and construction of foundations for various structures. Foundations are the parts of a structure that transfer the load from the superstructure to the underlying soil or rock. Foundations are essential for ensuring the stability and safety of any structure, as they prevent excessive settlement, differential settlement, uplift, sliding, overturning, and other failure modes.

Definition and Scope

According to Bowles (1996), foundation engineering can be defined as "the application of soil mechanics and rock mechanics (Geotechnical engineering) in the design of foundation elements of structures". The scope of foundation engineering includes the following aspects:

  • Site investigation and soil characterization

  • Bearing capacity and settlement analysis

  • Foundation selection and design

  • Foundation construction and testing

  • Foundation performance evaluation and improvement

Types of Foundations

There are two main types of foundations: shallow foundations and deep foundations. Shallow foundations are those that have a depth less than or equal to the width of the foundation. Deep foundations are those that have a depth greater than the width of the foundation. The choice of foundation type depends on various factors, such as the soil conditions, the load characteristics, the structural requirements, the economic considerations, and the environmental constraints.

Some examples of shallow foundations are:

  • Spread footings

  • Mat or raft foundations

  • Combined footings

  • Strip footings

  • Pile caps

Some examples of deep foundations are:

  • Piles

  • Caissons

  • Piers

  • Drilled shafts

  • Micropiles

Principles of Foundation Design

The main principles of foundation design are:

  • Safety: The foundation should be able to resist all possible failure modes and provide adequate factors of safety against them.

  • Serviceability: The foundation should limit the settlement and deformation of the structure to acceptable levels.

  • Economy: The foundation should be cost-effective and feasible to construct.

  • Sustainability: The foundation should minimize the environmental impact and optimize the use of natural resources.

Who is Joseph E. Bowles?

Joseph E. Bowles was a distinguished professor emeritus of civil engineering at the University of Illinois at Urbana-Champaign. He was also a prolific author, consultant, and educator in the field of geotechnical engineering.

Biography and Career

Bowles was born in 1924 in Chicago, Illinois. He received his B.S., M.S., and Ph.D. degrees in civil engineering from the University of Illinois at Urbana-Champaign in 1947, 1949, and 1954, respectively. He joined the faculty of the same university in 1954 and retired in 1992. He taught courses on soil mechanics, foundation engineering, and geotechnical engineering for over 38 years. He also served as the head of the Department of Civil Engineering from 1974 to 1981.

Bowles was a leading consultant in geotechnical engineering, working on numerous projects around the world. He was involved in the design and construction of foundations for buildings, bridges, dams, airports, highways, tunnels, and offshore structures. He also conducted research on various topics, such as soil-structure interaction, soil improvement, slope stability, retaining walls, and earth pressure.

Contributions to Foundation Engineering

Bowles was the author or co-author of more than 200 publications, including books, journal articles, conference papers, and technical reports. His most famous and influential work is the textbook Foundation Analysis and Design, which was first published in 1974 and has been revised and updated several times since then. This textbook is widely used by students, professors, and practitioners of foundation engineering around the world. It covers all aspects of foundation engineering in a clear and comprehensive manner, with numerous examples, problems, and case studies.

Bowles also contributed to the development of several standards and codes of practice for foundation engineering. He was a member of several committees and organizations related to geotechnical engineering, such as the American Society of Civil Engineers (ASCE), the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), the Transportation Research Board (TRB), and the National Academy of Engineering (NAE).

Awards and Honors

Bowles received many awards and honors for his outstanding achievements and contributions to foundation engineering. Some of them are:

  • The Norman Medal from ASCE in 1962

  • The Terzaghi Award from ASCE in 1975

  • The Karl Terzaghi Lecture from ASCE in 1982

  • The Distinguished Service Award from ISSMGE in 1985

  • The Outstanding Educator Award from ASCE in 1988

  • The Ralph B. Peck Award from ASCE in 1995

  • The election to the NAE in 1996
