Abstract

Introduction:

The design of direct embedment pole foundations involves calculating the ultimate moment capacity and deflections/rotations of pole foundations at groundline.

Methods:

A theoretical model based on rigid piles is used as a basis for developing equations for the ultimate moment capacity of direct embedment pole foundation installed in granular soils.

Results and Conclusion:

The steps involved in the development are presented in this paper. Prototype test data are used to compare the predictions of the model and to validate the proposed method.

Keywords: Direct embedment, Moment capacity, Pole foundations, Granular soils, Rigid piles, Prototype.
