摘　　要：海底管道常常受本身自重和各种动力因素的作用,以及海底沉积物的运移而造成部分被埋入海底。通过对这类部分埋设管道在波流作用下的水动力效应的实验研究,发现其中的曳力和惯性力有很大程度的减小,但升力的减小并不十分明显,而升力频率变化为入射波频的1～4倍。Sub - sea pipelines are generally buried on sea floor due to the actions of its own weight and various dynamic forces as well as sediments. Through experimental research on the wave and current effects to buried pipelines, it is found that there is great reduction of drag and initial force but less obvious increase of lift force frequency, and the increase of lift force requency is 1 - 4 times of the incident wave frequency.
