| 摘 要： | 海底管道施工质量直接关系到海底管道能否长久地安全运行,对施工期间各种环境载荷、施工载荷作用下海底管道上的应力进行计算分析是确保海底管道施工质量不可缺少的重要手段.从海洋管道漂浮拖运过程受力-极限情况入手,建立数学模型,首次应用五弯矩方程解决海洋管道在拖运过程中的受力问题.并开发了实用程序,算例表明:计算分析结果满足实际应用要求.

| Abstract: | It is an important means to ensure the construction quality of submarine pipeline that to calculate and analyze the stress of every kind of environmental load and construct load during construct. The article introduces the force effect on marine pipelines under extreme working situations when float towing, founds mathematical model. It is also the first time to present the way to analysis the force in limit case effect on the marine pipelines during float towing with the help of five-movement equation, and develop practical program, The example shows the results are satisfactory. |
