埋地管道抗震设计

摘要

院埋地管道抗震设计的控制要素是受外力作用下的管道变形以及由此而形成的分段管道接点之间的相对位移，分析了由地震引起的管道变形和相对接点位移的上限。本文提出了用伪静力分析的模型来研究各种物理作用，地质学以及地震学参数的结构抗震设计。%The control elements of the seismic design of buried pipelines is the tube deformation and the relative displacement between the segment pipeline junction affected by the under external force. This paper analyzes the caps of the tube deformation and the relative joint displacement caused by earthquakes. This paper presents a pseudo-static analysis model to study various physical role, geology and seismology parameters seismic design.
