等效离散型海底管道模型试验方法研究

Study on equivalent discrete offshore pipeline model testing method

随着研究水深的增加,国内现有试验水池难以完成水深2 000m以上的深水海底管道铺设试验,因此提出了等效离散型管道模型试验方法。分别对等效离散型管道模型试验方法和连续型管道模型试验方法进行了理论分析,以及2 000m水深海底管道铺设水池试验,2种模型的理论分析及水池试验结果较为接近,验证了本文提出的等效离散型海底管道模型试验方法的可行性。

With the increase of the deepwater research,the testing basin existing in our country is difficult to do the basin test for the deepwater（more than 2000 meters） pipe laying,so the equivalent discrete model testing method was proposed.Theoretical analyses have been carried out respectively to equivalent discrete pipeline model testing method and conventional pipeline model testing method,and the basin test have been conducted for laying the 2000m deepwater pipeline.The theoretical analyses of the two methods and the results of basin testing are similar relatively,which is verified that the equivalent discrete model testing method presented in this paper is feasible.
