海底输水管道内力分析
|
摘要
由于所处环境和施工条件的特殊性,海底输水管道内力计算较陆上管道有较大差别,目前暂无规范或手册对其进行系统的讨论。本文利用材料力学理论对海底输水管道在特定荷载作用下的内力进行计算,对各工况下的内力进行组合,并推导了海底管道可能发生屈曲失稳的计算公式。相关过程可供类似项目的设计人员参考。
Due to the particularity of the environment and construction conditions, the calculation of the stress of the submarine water pipeline is quite different from that of the onshore pipeline. Howerer there is no specification or manual for relevant engineers to reference. In this paper, the material mechanics theory was used to calculate the stress of submarine water pipeline under specific load, and the stress under various working conditions were studied and integrated. Then the calculation formula of buckling instability of submarine pipeline was deduced. The results should be referenced by designers of similar projects.
