本文用“埋地长输管道热胀内力近似分析”一文所提出的弹性抗弯铰模型,应用纵横弯曲弹性地基梁理论,分析了两臂不对称埋地长输管道水平弯头的热胀内力和位移。并对两臂对称埋地水平弯头及锚固墩的过渡段长度进行了讨论。文中还通过算例说明了有关的计算过程。
In this paper, the elastic bending hinge model proposed in the article “Approximate analysis of thermal expansion internal force of buried long-distance pipeline” was used to analyze the thermal expansion internal force of horizontal elbow of asymmetrical buried long-distance pipeline And displacement. The length of the transition between two symmetrical buried horizontal elbows and anchor piers is discussed. The article also illustrates the calculation process through examples.
