FM 5-134 C H A P T E R 1 B A S I C C O N S I D E R A T I O N S Section I. DEFINITIONS AND CLASSIFICATIONS 1-1. Definitions. a. Piles. A pile is a long, columnar element made of timber, steel, concrete, or a combination of these materials (discussed in chapter 2). Piles transmit foundation loads to deeper strata that sustain the loads safely and prevent settling of the supported structure. Piles derive their support from a combination of skin friction along the embedded lengths and end bearing at the tips or bottoms (figure l-l). b. Piers. A pier is a pile used to support a horizontal supporting span such as a bridge or archway. c. Sheet piles. Sheet piles are generally prefabricated or precast members driven vertically into the ground to form a continuous vertical wall. Sheet piles protect bearing piles against scour and the danger of undermining a pier foundation (figure 1-2).
