Abstract
This paper presents the observations drawn from an experimental model testing program conducted on laterally loaded free head flexible piles embedded in two layered sandy strata consisting of medium and dense sand in top and bottom layers respectively. The parameters involved in the study were surface roughness, sand layer thickness and type of load acting on the pile. The effect of variation of these parameters on the lateral capacity of piles is discussed in this paper. The lateral load capacity was observed to be adversely affected with increase in the thickness of top layer containing sand of medium density. The relationship between the two parameters was found to be non linear and exponential. Piles with rough surface showed improved lateral stiffness as compared to piles with smooth surface with maximum improvement observed for single piles. Combined vertical and lateral load on pile resulted in increased lateral displacement and slightly increased bending moment as compared to the lateral load acting alone.
