In　order　to　improve　the　ability　of　the　reinforcement　concrete　(RC)　pile　foundation　of　integral　abutment　to　absorb　the　horizontal　reciprocating　deformation　under　the　action　of　temperature　or　earthquake,　a　pseudo-static　low　cycle　test　on　interaction　of　pile-soil　with　high　reinforcement　ratio　was　carried　out.　The　failure　location,　hysteresis　curve,　skeleton　curve　and　horizontal　deformation　of　three　piles　with　different　reinforcement　ratios　were　compared.　The　test　results　show　that,　with　the　increase　of　the　reinforcement　ratio,　the　crack　of　the　RC　pile　develops　along　the　pile　body　to　the　depth,　and　the　pile　body　failure　area　and　the　position　where　the　maximum　bending　moment　moves　down,　the　crack　resistance　of　the　pile　body　is　improved,　and　the　effective　interaction　pile　length　increases;　The　test　results　also　show　that　the　hysteresis　curve　of　the　model　pile　becomes　fuller　with　the　increase　of　the　reinforcement　ratio,　compared　with　the　RCP-1　specimen　with　the　lowest　reinforcement　ratio,　the　equivalent　viscous　damping　ratio　of　the　RCP-3　specimen　is　increased　by　31.6%,　and　the　energy　dissipation　capacity　is　improved.　In　addition,　with　the　increase　of　the　reinforcement　ratio,　the　bearing　capacity　and　deformation　capacity　of　model　piles　are　greatly　improved.　Compared　with　RCP-1　specimen,　the　ultimate　bearing　capacity　of　RCP-3　specimen　increased　by　150%,　and　the　corresponding　ultimate　displacement　increased　by　153%.　Increasing　reinforcement　ratio　can　significantly　improve　the　mechanical　properties　and　deformation　capacity　of　RC　pile.　©　Content　from　this　work　may　be　used　under　the　terms　of　the　Creative　Commons　Attribution　3.0　licence.
