Batter　piles　are　often　designed　as　foundation　of　high-rise　structures　to　resist　large　lateral　loads.　The　sizeable　overturning　moment　of　the　superstructure　will　be　transferred　to　the　foundation　so　that　batter　piles　are　subject　to　the　oblique　uplift　loading　with　changing　directions.　Due　to　the　lack　of　understanding　of　the　working　behavior,　the　design　and　application　of　the　oblique　uplift　batter　pile　are　limited.　In　this　study,　11　groups　of　laboratory　tests　are　carried　out　in　a　testing　box.　The　instrumental　batter　piles　are　made　of　polyvinylchloride　pipes　and　loaded　via　pulley　and　counterweight.　The　variation　of　internal　force,　pile　deformation,　and　load-displacement　curve　of　the　pile　head　is　acquired.　The　load　transfer　mechanism　and　failure　mode　are　summarized.　A　new　type　of　tactile　pressure　sensor　(TPS)　is　attached　to　the　pile　surface,　and　the　actual　pile-soil　interaction　forces　in　the　normal　direction　are　measured.　The　results　show　that　the　loading　angle　alpha　controls　the　overall　stability　of　the　pile,　the　critical　angle　is　15　degrees　(in　this　study,　qualitatively).　When　the　alpha　is　within　+/-　15　degrees,　the　axial　component　of　the　oblique　uplift　load　controls　the　overall　stability　of　the　pile;　otherwise,　the　lateral　component　controls　the　stability.　The　increase　of　the　loading　angle　alpha　will　increase　both　the　bending　moment　of　the　negative　and　positive　batter　pile,　but　with　different　increments.　The　increase　of　pile　inclination　beta　will　weaken　the　bending　moment　concentration　effect.　The　soil　pressure　on　the　batter　pile　is　in　the　offset　state,　which　can　be　fitted　by　elliptic　function.　The　pile-soil　interaction　below　a　certain　depth　is　not　affected　by　the　pile　inclination　beta　and　loading　angle　alpha.　The　middle　to　lower　sections　of　the　batter　pile　can　be　designed　as　the　axial　uplift　pile,　considering　its　resistance　of　axial　skin　friction　only.　This　study　shows　the　working　mechanism　of　the　oblique　uplift　batter　pile　in　a　manner　way,　which　has　practical　significance　for　design　and　engineering　application　of　batter　pile.
