摘　　要：由于良好的管线下放形态,J型铺设是目前大管径深水海底管道最适用的铺设方式。针对大直径海底管道J型铺设下放过程,本文采用悬链线理论进行管道铺设静态分析,探究铺设角度和水深对管线受力的影响,以确定大直径海底管道在不同作业水深的最佳铺设角度。基于商业软件Orca Flex开展管道铺设过程中时域动态分析,研究铺管船运动、海洋环境及管道破损状态下管道上张力和应力变化情况,可为实际工程提供参考。J-Lay system has been the most suitable laying method for large diameter subsea pipeline at present because of its advantageous pipeline laying form.In the process of laying large diameter submarine pipeline with J-Lay system,the effect of laying angle and water depth on the pipeline is of critical importance.Therefore,based on the catenary theory,the static analysis considering the factors above is carried out in order to determine the suitable laying angle of large diameter submarine pipeline under different water depths.In addition,the time domain dynamic analysis is conducted to study the influence of ship motion,current incidence angle and existing pipeline damage on the dynamic stress of pipeline.The results can server as reference for engineering practice.
