Introducing　an　integral　abutment　into　a　skewed　bridge　to　form　a　skewed-integral-abutment　bridge　(SIAB)　can　improve　the　in-plane　torsion　and　the　beam　drop　phenomenon　of　a　superstructure　during　an　earthquake.　Owing　to　the　integration　of　the　girder　and　abutment,　complicated　abutment-pile-soil　interactions　occur　when　the　SIAB　suffers　from　seismic　load.　A　pseudo-static　cyclic　test　on　the　behavior　of　a　skewed-integral-abutment-steel-H-pile-soil　system　was　conducted　based　on　an　existing　integral-abutment　bridge.　The　seismic　performance　of　the　skewed-integral-abutment-steel-H-pile-soil　system,　the　distribution　of　backfill　pressure,　and　the　horizontal　deformation　of　the　steel　H-pile　were　studied.　The　test　results　indicate　that　the　skewed-integral-abutment-steel-H-pile-soil　system　has　an　excellent　energy　dissipation　capacity　and　ductility.　The　backfill　has　a　significant　effect　on　the　seismic　performance　of　the　system.　Backfill　increases　the　lateral　bearing　capacity　and　stiffness;　however,　it　makes　the　residual　force　and　displacement　asymmetrical　when　loading　in　the　positive　and　negative　directions.　During　positive　loading,　the　lateral　bearing　capacity　and　stiffness　are　higher,　however　the　residual　bearing　capacity　and　residual　displacement　are　lower.　When　the　displacement　is　small　(　©　2022　Xi＇an　Highway　University.　All　rights　reserved.
