A deep fill of varying thickness will settle with time and will also exhibit a horizontal component of movement. Drilled shafts that are installed in the fill to support a structure must be designed to accommodate downdrag and lateral forces. Soil-structure-interaction concepts are utilized in developed a rational solution to the problem. The principal tool was a computer program that utilized modified p-y curves.
