摘　　要：油气管道是国家工业生产、人民生活的重要能源设施,一旦遭遇地震破坏将造成重大危害与损失,如何提高油气管道的抗震能力尤为重要。利用大型通用有限元软件ANSYS10.0模拟分析天然气管道在仅有内压情况下的地震动力反应。结果表明:不同埋土条件对管道地震反应影响很大,管道内压、管径等对其影响较小。研究成果为埋地天然气管道的抗震研究提供依据。Natural gas pipeline was an important energy facility concerning China's industrial production and people's life,if it was damaged by earthquake,it would induce serious hazards and losses,therefore it was very important to improve the anti-earthquake ability.A powerful finite element software ANSYS was used to simulate its dynamic earthquake reaction under the condition of internal pressure.The result shows that different burial conditions have different earthquake reactions on the pipeline,its internal pressure and diameter has less influence on it.It provides basis for studying the anti-earthquake of the buried gas pipeline.
