With the development of mountainous area, pile foundation has been used as mitigation slope movement. Raked piles used in a group pile subjected to lateral forces are common. In this study, we used the FLAC3D program to analyze the mechanical response of a raked pile subjected to lateral soil movement. In order to verify the correction of the FLAC3D simulation, its validation was compared with a published case study. Then the analysis of a single pile and a one row-pile in different dip angles subjected to lateral soil movement were modeled. Results of the analysis show that raked pile under the conditions of lateral slope movement will cause the pile’s lateral displacement and bending movement to increase. A row raked pile used can reduce the lateral displacement of the pile. Further study is required to evaluate the raked pile behavior subjected to lateral slope movement.
