针对随机波浪作用下海底管线的动力响应是设计中需考虑的重要因素，考虑波浪随机特性、管-土接触和惯性效应，建立了二维有限元管-土相互作用的数值计算模型，开展了摩擦系数、埋深、管径、海床渗透系数对管周孔隙水压力、管线竖向位移及其内部正应力影响的数值模拟研究。研究成果可为海底管线设计提供技术参考。
針對隨機波浪作用下海底管線的動力響應是設計中需攷慮的重要因素，攷慮波浪隨機特性、管-土接觸和慣性效應，建立瞭二維有限元管-土相互作用的數值計算模型，開展瞭摩抆繫數、埋深、管徑、海床滲透繫數對管週孔隙水壓力、管線豎嚮位移及其內部正應力影響的數值模擬研究。研究成果可為海底管線設計提供技術參攷。

It is a key issue to define the dynamic response of buried submarine pipeline subjected to random wave loading in the design of submarine pipelines .Taking the stochastic behavior of waves ,contact and inertia effects into considera-tion ,a 2-D finite element analysis model was established considering pipeline-soil interaction ,based on which ,the influ-ence factors including frictional coefficient ,buried depth ,pipe radius and permeability of seabed were analyzed to study the impacts on pore pressure ,vertical displacement and normal stress of the pipes respectively .The derived conclusion provides a technical support for the design of submarine pipelines .
