Foundation Engineering Handbook - Robert W. Day





1.1 DEFINITIONS

A foundation is defined as that part of the structure that supports the weight of the structure and

transmits the load to underlying soil or rock. In general, foundation engineering applies the knowledge

of geology,

soil mechanics, rock mechanics, and structural engineering to the design and construction

of foundations for buildings and other structures. The most basic aspect of foundation

engineering deals with the selection of the type of foundation, such as using a shallow

or deep foundation system. Another important aspect of foundation engineering involves

the development of design

parameters, such as the bearing capacity or estimated settlement of the foundation. Foundation

engineering

could also include the actual foundation design, such as determining the type and spacing

of steel reinforcement in concrete footings. Foundation

engineering often involves both geotechnical

and structural engineers, with the geotechnical engineer providing

the foundation design parameters such as the allowable

bearing pressure and the structural engineer performing the actual foundation design.
