In　order　to　solve　the　problem　of　backward　seismic　design　of　buried　pipeline　crossing　fault,　a　seismic　design　method　based　on　performance　is　proposed.　Taking　the　seismic　fortification　standard　of　buried　steel　pipelines　as　the　starting　point,　and　the　pipeline　failure　probability　as　the　measurement　index　to　divide　the　pipeline　performance　level,　the　performance　targets　of　different　function　classes　of　pipelines　under　different　fortification　earthquakes　are　proposed.　For　the　single　pipeline,　the　Newmark-Hall　theory　calculation　method　is　used　to　establish　a　performance　function　based　on　the　allowable　length　change,　and　the　importance　coefficient　is　calculated　based　on　the　principle　of　improving　a　behavior　level.　Considering　the　simplification　of　Newmark-Hall　model　and　the　lack　of　nonlinear　analysis,　the　influence　of　five　parameters,　such　as　buried　depth,　pipe　diameter,　wall　thickness,　pipe-soil　friction　coefficient　and　grade　of　pipe,　on　the　axial　tensile　strain　and　compressive　strain　of　pipe　is　analyzed　by　using　nonlinear　finite　element　method,　and　a　performance　function　based　on　allowable　strain　is　established　according　to　the　fitted　pipeline　maximum　strain　regression　formula,　and　the　importance　coefficient　is　compared　and　verified.　The　results　show　that　the　two　calculation　results　are　consistent,　which　provide　accurate　parameters　for　the　design　of　buried　pipelines　across　faults,　and　provide　a　preliminary　idea　for　the　realization　of　performance-based　seismic　design.　©　2023　Editorial　Board　of　Journal　of　Basic　Science　and.　All　rights　reserved.
