Abstract
Oil pipeline is the important facility of military rear oil depot.For further research of seismic re-sponse of buried pipeline,soil spring analysis model was established based on finite element software Abaqus.Using orthogonal experiment method,several common types of pipelines in military rear oil depot were selected to calculate the seismic response.The influence of factors such as diameter of pipeline,wall thickness and inner pressure on the peak value of von Mises stress was studied.The results showed that the change of the von Mises stress of different types of pipelines under seismic action was basically the same,the peak value of von Mises stress appeared at the fixed end of pipeline;increasing the diameter of pipeline,the value of von Mises stress changed little;increasing the wall thickness,the peak value of von Mises stress reduced significantly;increasing the inner pressures,the peak value of von Mises stress re-duced.The results of the study has certain guiding significance on seismic design of pipeline.关键词
