Study on the Submarine Pipeline with Flexible Spoilers

摘要：

　　Two new methods which use flexible spoilers to protect submarine pipelines are proposed.One is put flexible spoiler on the top of the pipe to make pipe self-buried.The other is put flexible spoiler under the pipe to stop the erosion under the pipe.Through physical experiments,the pressure distribution and scour hole around the submarine pipeline with flexible deflectors were studied.Experiment results point out that top flexible spoiler can increase the resistance of the pipe,increase the scour hole depth,accordingly make the pipeline be self-buried.The flexible spoiler under the pipe can reduce the pressure difference between both sides of the pipeline,diminish the scour hole depth obviously and even to stop scour.
