海底管道水动力和在位稳定性研究的近代进展

The Modern Development of the Research of Submarine Pipelines Hydrodynamic Forces and On-Bottom Stability

海洋工程中海底管道为保证其正常运行和结构生存期的安全,直接与海底管道水动力和在位稳定性研究密切相关的。本文着重叙述了70年代、80年代国外对接近于海底、部分埋入海底和海底敞口浅沟内管道的水动力和在位稳定性方面的研究结果,并就进一步开展这方面研究进行讨论。

In ocean engineering the normal operation and the structural safety of the submarine pipelines are related with the pipeline hydrodynamic forces and on-bottom stability,This paper illustrates the developments of the hydrody- namic forces and on-bottom stability research of the pipeline near the seabed, partially buried and in open trench in the world in 1970's and 1980's,and discusses the further research.
