In the analysis of soil-pile interaction under lateral load, the effect of the embedded length of a pile is an important parameter which has a significant influence on its lateral load capacity. This paper investigates the effect of embedded length of a single pile on its ultimate lateral load capacity. In this research, a 30mm steel rod pile was used, and four embedment lengths were selected (250, 300, 350, and 400 mm) for embedment ratios (length to diameter, L/D) = 8.3, 10, 11.7 and 13.3, respectively. The pile was embedded in three different relative densities of sand (loose, medium, and dense). The tests were performed using constant rate displacement method. The results indicate that there is an increase in the capacity of laterally loaded pile up to 247% when embedded ratio (L/D) increases from 8.3 to 13.3 and when the relative density increases from 12% to 85% there is an increase up to 599% in the resistant capacity of the pile.
