Seismic　hazards　indicated　that　buried　pipelines　were　damaged　more　easily　in　complex　stratum　structures.　In　this　paper,　based　on　the　finite　element　software　ABAQUS,　the　seismic　responses　of　buried　pipeline　in　two　Heterogeneous　stratum　fields　were　studied,　including　valley　stratum　field　and　horizontal　soft　stratum　structures　field.　Firstly,　the　key　to　build　three-dimensional　finite　element　numerical　simulation　model　were　talked　about,　including　the　Artificial　Boundary　Condition　to　simulate　the　energy　radiation　for　the　opening　system,　the　description　of　interface　contact　between　soil　and　pipeline,　and　the　constitutive　model　of　material.　Then,　two　three-dimensional　finite　element　numerical　simulation　models　were　established　respectively,　considering　the　characteristics　of　the　two　stratum　fields.　Finally,　the　seismic　response　of　buried　pipelines　was　analyzed,　and　the　effect　of　influence　factors　on　the　seismic　response　of　buried　pipeline　was　studied.
