| 中文摘要 | One of the main concerns for pipeline on-bottom stability design is to properly predict ultimate soil resistance in severe ocean environments. A plane-strain finite element model is proposed to investigate the ultimate soil resistance to the partially-embedded pipeline under the action of ocean currents. Two typical end-constraints of the submarine pipelines are examined, i.e. freely-laid pipes and anti-rolling pipes. The proposed numerical model is verified with the existing mechanical-actuator experiments. The magnitude of lateral-soil-resistance coefficient for the examined anti-rolling pipes is much larger than that for the freely-laid pipes, indicating that the end-constraint condition significantly affects the lateral stability of the untrenched pipeline under ocean currents. The parametric study indicates that, the variation of lateral-soil-resistance coefficient with the dimensionless submerged weight of pipe is affected greatly by the angle of internal friction of soil, the pipe-soil friction coefficient, etc. |
