摘　　要：对置于海底开敞的沟槽内管道受到波流作用下的水动力具有的掩护效应进行了实验研究 ,发现水动力中的曳力和惯性力有很大程度的折减 ,升力的折减不大 ,水动力的折减程度在一定范围内还与沟槽宽度。An experimental study was carried out for the hydrodynamic shelter effect on the submarine pipeline in open trench under the action of wave and current.It has been shown that the towing force coefficient C D and lifting force C L are obviously related to the Kc number and usually they decrease with the increase of Kc number and gradually reach their own steady values.The inertia force coefficient C M various between 1 5.
