LABORATORY STUDY OF THE BEHAVIOR OF PILE GROUP SUBJECTED TO LATERAL LOADS IN SANDY SOIL

This study is concerned with identifying the deflection of pile groups subjected to lateral load and the corresponding soil failure. A digital photogrammetric system is adopted for studying the field deformations. A wide range of studies was carried out to investigate the effect of some parameters on the behavior of the pile group. These parameters are effect of spacing between piles, number of piles, piles slenderness ratio and soil density. Using the experimental model results, relations were deduced to estimate the lateral deflection of pile group. A comparison is done between these relations and some relations given in the literature.
