This course will provide you with an introduction to deep foundations. A deep foundation derives its support from competent strata at significant depths below the surface or, alternatively, has a depth to diameter ratio greater than 4. A deep foundation is used in lieu of a shallow foundation when adequate bearing capacity or tolerable settlements cannot be obtained with a shallow foundation. The term deep foundation includes piles, piers, or caissons, as well as footings or mats set into a deep excavation. This publication discusses problems of placing footings and mats in deep excavations and design of drilled piers. Drilled piers (or caissons) are simply large-diameter piles, but the design process is somewhat different. An arbitrary distinction between a caisson and pier is that the caisson is 30 inches or more in diameter.

7. FOUNDATION SELECTION CONSIDERATIONS
Upon completion of this course you will:
Learn the definition and design considerations applicable to floating foundations;
Learn the mechanics of settlement of compensated foundations;
Learn when there is a likelihood of bearing capacity failure;
Learn two commonly used procedures to mitigate bottom heave; and
Learn about settlement issues adjacent to excavations.
This course is intended for civil engineers, structural engineers, geotechnical engineers, geologists and other design and construction professionals wanting an introduction to deep foundations for buildings and other structures.
