The　investigation　of　earthquake　damage　shows　that　the　lateral　spread　of　gently　inclined　soil　is　a　common　form　of　foundation　failure.　As　the　concrete　pile　has　a　high　vertical　bearing　capacity　and　shear　resistance,　and　the　stone　column　has　a　high　permeability,　which　can　effectively　reduce　the　degree　of　liquefaction　of　the　surrounding　soil,　whether　the　concrete-stone　composite　pile　can　be　used　as　an　effective　engineering　measure　to　deal　with　the　large　lateral　deformation　of　liquefaction　in　gently　inclined　soil,　its　feasibility　is　worthy　of　in-depth　research.　Therefore,　the　numerical　model　of　liquefiable　soil-pile　foundation　is　established　based　on　OpenSees　finite　element　platform,　then　the　reliability　of　the　numerical　model　is　rerified.　On　this　basis,　the　reinforcement　effect　of　concrete-stone　composite　pile　on　inclined　liquefaction　soil　is　studied.　In　addition,　the　effects　of　area　ratio　of　core　pile　and　thickness　of　stone　shell　on　dynamic　response　of　inclined　liquefaction　soil　are　discussed.　The　results　show　that　the　concrete-stone　composite　pile　has　a　significant　anti　lateral　displacement　effect,　which　can　effectively　reduce　the　lateral　displacement　of　the　surrounding　soil　and　the　bending　moment　of　the　concrete　core　pile.　When　the　proportion　of　concrete　core　of　pile　body　is　about　20%　and　the　proportion　of　stone　shell　area　is　80%,　it　is　the　optimal　design　scheme.　©　2024　Editorial　office　of　Earthquake　Engineering　and　Engineering　Dynamics.　All　rights　reserved.
