In practice, Pile foundations mostly consist of a group of piles and usually subjected to a combination of vertical and lateral loads. Specifically, pile groups support a combination of vertical due to superstructure gravity, lateral loads during an earthquake. One of important design criteria under such loading conditionsis to control the lateral deflection of the pile group. In this article, using numerical analyses by FLAC3D finite difference software, the lateral deflection of pile group in sandy soils under combined loading have been evaluated and compared with the ultimate lateral deflection of the pile group. The research resultsindicated that lateral deflection of pile group depends on combination of loading omponents as well as the type of pile response under lateral loading. The effect of pile spacing and pile geometry on the pile group deflection was also considered.<\div>
