摘要

利用接触单元对埋地管线及土体进行三维实体建模,并对地震荷载作用下的管线进行了应力计算,给出了最大轴向应力;对比了规范方法、理论方法、梁-土弹簧模型以及管土接触模型的四种计算结果,表明现有简化模型的计算结果偏小,偏于不安全。
Three-dimensional finite element model of buried pipeline and soil was set up based on pipe-soil contatct mode.Stress of pipeline under seismic load was calculated and the maximum axis stress was obtained.Results showed that the existing simplified models were smaller and unsafe after comparison of the four methods,standard method,theory method,beam-soil-spring model and pipe-soil contact model.
