Batter　piles　often　bear　high　horizontal　resistance　and　oblique　uplift　load　transformed　from　high-rise　superstructures,　and　the　direction　of　the　oblique　uplift　load　changes　with　the　horizontal　displacement　of　the　superstructure.　However,　the　working　behaviour　of　batter　piles　under　such　working　conditions　is　less　understood.　Therefore,　a　series　of　laboratory　and　numerical　studies　is　carried　out.　A　new　type　of　tactile　pressure　sensor　is　also　used　to　measure　the　soil　pressure　around　the　pile.　Three　major　conclusions　are　summarised　from　the　results.　First,　the　lateral　response　of　the　batter　pile　is　affected　by　the　loading　angle,　while　the　axial　response　is　not.　Second,　the　at-rest　soil　pressure　on　the　batter　pile　is　in　the　＇offset＇　state,　which　can　be　fitted　with　an　elliptic　function.　The　pile-soil　interaction　below　a　certain　depth　is　not　affected　by　the　pile　angles,　and　the　pile　can　be　designed　as　the　axial　uplift　pile.　The　soil　stiffness　varies　within　0.4L　and　5D　in　the　axial　and　radial　directions　of　the　pile,　respectively.　The　increase　in　pile　inclination　and　loading　angle　can　reduce　the　stiffness　degradation　to　a　certain　degree.　The　findings　of　this　research　can　support　engineering　practice　in　the　design　of　batter　piles.　©　2023　Published　with　permission　by　the　ICE　under　the　CC-BY　4.0　license.　(.
