| 摘 要： | 管道悬垂是一种简单且应用广泛的管线跨越方式，水流冲刷等地质灾害也会造成埋地管线部分悬空。本文充分考虑了管-土相互作用和支座非线性因素的影响，采用非线性增量有限元方法对悬垂管道跨越结构在地震作用下的反应进行了分析。

| Abstract: | Spanning structure of suspended pipelines is simple and widely used. Suspended parts of buried pipelines may be formed due to geologic disastersuch as current scour. Pipe-soil interaction and movable supports influencing seismic response of suspended pipeline are investigated and seismic responses of free spanning are analyzed by nonlinear finite element method. |

| Keywords: | suspended pipeline pipe-soil interaction seismic response |
