摘　　要：介绍海底管道沉降的发展过程。基于太沙基一维固结理论,以Boussinesq应力解的分层总和法完成海底管道在黏性土质海床下固结沉降量的计算。为验证计算结果的准确性,借助有限元分析软件Abaqus对某工程实例进行数值模拟求解,结论表明公式计算与数值求解得到的结果具有较好的吻合性。研究内容对海底管道的设计与分析具有参考意义。The development process of offshore pipeline settlement is introduced.Based on one dimensional consolidation theory proposed by Terzerghi,through the stress analysis of Boussinesq and splitting summation method,the consolidation settlement of the offshore pipeline on the cohesive soil sea bed is studied by in-house program.To verify the accuracy of the calculation results,the finite element analysis software Abaqus is introduced.The results show that the calculation results are in good agreement with the numerical results.The research is of reference significance for the design and analysis of submarine pipeline.
