| 摘 要： | 为丰富对活动断层作用下海底管道的受力特性认识,考虑管土材料非线性与几何非线性特征,采用通用有限元软件ABAQUS严格模拟管土之间的相互作用;按照应变控制准则,结合管道屈曲破坏、极限拉伸破裂等的破坏形式,系统分析了海底走滑断层作用下管道在不同设计参数情况下的位移、应力应变分布情况,得到了不同条件下管道发生破坏时的极限断层位移。最后基于分析结果提出了适用于海底管线设计和运营的一些建议。

| Abstract: | To get some insight into the response of the submarine pipelines crossing active strike-slip faults, the interacting soil-pipeline system is modeled on the platform of finite element software ABAQUS. Nonlinear material behavior and large strains and displacements for both pipelines and soils are considered. With the buckling and the fracture of the pipeline included, the paper employs the strain-based criterion to obtain the distribution of the displacement, stress and strain along the pipeline, and the critical displacement of pipeline under various conditions. Finally, suggestions on submarine pipeline design and operation are given based on the analysis. |
