scope:

General information with respect to the selection and design of deep foundations is addressed herein. Single and groups of driven piles and drilled shafts under axial and lateral static loads are treated. Some example problems and the most widely accepted computer methods are introduced. This publication is not intended for hydraulic structures; however, it does provide the following:

a. Guidance is provided to assist the efficient planning, design, and quality verification of the deep foundation.

b. Guidance is not specifically provided for design of sheet piles used as retaining walls to resist lateral forces or for the design of stone columns.

c. Guidance for construction of deep foundations is provided only in minor detail.

Purpose. This publication presents data, principles, and methods for use in planning, design, and construction of deep foundations. Deep foundations are literally braced (supported) column elements transmitting structure loads down to the subgrade supporting medium.

Applicability. These instructions are applicable to all HQUSACE elements and USACE comands.
