摘要：Snaked-lay method is an effective lateral buckling control method, for design of snaked-lay pipeline the key is to control lateral buckling of pipeline. Namely, the lateral buckling is triggered at the designed location, the moment and strain of post-buckling are acceptable. A new shape of snaked-lay pipeline is presented, based on ANSYS, nonlinear finite element model of exposed pipelines laid on even seabed is built. Post-buckling of pipeline is studied, effect of sine length, snaked-lay radii and offset angle are all included. Based on analysis, a control criterion of offset angle is also presented. ? 2012 Binary Information Press.
