Description	Here, horizontal loading tests on spiral piles and cylindrical piles were conducted. The model ground was made using dry sand. Model piles were arranged in a row on the model ground; a wire was attached to the pile head and loaded monotonically in one direction. The experiment was conducted for five cases, with the center-to-center spacing of the piles changing from 1.5 times to 8 times the pile diameter. The results revealed that the tendency of the pile group effect of the spiral pile varied vastly depending on the evaluated load level. At the initial loading stage, spiral piles were more affected by the pile group effect than ordinary cylindrical piles; the relatively large initial displacement should be considered while designing spiral piles. However, as the loading progressed, spiral piles tended to have a smaller reduction in bearing capacity than the cylindrical piles owing to the pile group effect.
