摘要

确定波浪荷载作用下海底埋置管线和海床的响应是海底管线设计中的关键问题。目前大多数研究只是考虑了管线、海床在线性推进波作用下的响应，并没有考虑管线与海床之间的相互作用效应。采用接触摩擦理论，考虑管线与海床之间的相互作用效应，基于有限元方法研究了非线性波浪作用下海底埋置管线和多孔海床相互作用问题。数值计算结果表明，在计算中如果忽略波浪非线性项，既有可能低估海底管线内应力及管线周围海床中孔隙水压力，也有可能高估海底管线内应力及管线周围海床中孔隙水压力。

Abstract

It is a key issue to define the transient responses of submarine pipeline and seabed under wave loading in the design of submarine pipeline. Most previous investigations were only concerned with the soil response due to linear progressive ocean waves

and the effect of pipeline-seabed interaction on internal stresses within the pipeline are not well recognized. The pipeline-seabed interaction under nonlinear wave loading is investigated by using friction contact theory and the finite element method. Numerical results demonstrate that if the effect of non-linear wave components is neglected

the internal stresses in the pipeline and pore pressure in the seabed may be underestimated or overestimated probably.
