Abstract Both centrifuge modeling and numerical simulation are employed to investigate pile-soil-pile interaction between two adjacent piles with pile spacing of 3 times pile diameter moving in different directions. The influence of pile spacing，internal friction angle of sand，and different displacements of the leading and trailing piles on reduction factor are also analyzed based on numerical results. It is found that pile-soil-pile interaction is significant in two adjacent piles undergoing different movement directions. The reduction factor of the trail pile is not larger than that of the leading one in the investigated two cases. It is also found that reduction factors for the leading and trail piles almost linearly increase as pile spacing varies from 3 times pile diameter to 5 times and almost keep constant with internal friction angle. In addition，loading mode has certain effect on reduction factors of the two piles.

Key words： pile foundations pile-soil-pile interaction reduction factor eccentric lateral loading group pile centrifuge modeling
