【 摘 要 】

The snaked laying is an effective method to control the submarine pipeline lateral buckling and widely used in the pipeline projects. In order to control the lateral buckling, the snaked lay method is investigated theoretically and numerically. Because of the special configuration of the snaked laying pipeline routine, the lateral global buckling can be easily triggered with a small compressive stress and the bending stress on the pipeline cross-section can be maintain at a low level. This paper analysed the impact factors of snaked laying pipeline on the lateral global buckling especially the laying wavelengths, amplitudes of curve and curve shapes. And the comparison between snaked laying and regular laying pipeline are discussed.
