计算机技术在海底管道施工中的应用

The Application of Computer Techniques in the Sub Sea Pipeline Constructive

在海洋工程领域中，计算机技术在众多方面所表现出来的优越性对于海底管道的施工颇具指导意义，本文从滩浅海油田开发的现状入手，从提高和完善海底管道施工技术的角度，提出了采用计算机技术辅助海底管道施工及防护的新思路，详细阐述了计算机技术在海底管道稳定性分析，海底管道凸起及悬跨应力分析、海底管道涡激振动分析、海底管道立管结构预制及起吊分析等方面所开发的软件的工作原理和对海底管道施工及防护的辅助作用，并进一步说明了这些软件的运行过程和应用效果。

In the ocean construction field, the superiorities displayed by computer techniques in several aspects are very guidable to the sub sea pipeline constructive. This article starts with the present situation of the offshore oil development, puts forward the new train of thoughts of assisting the sub sea pipeline constructive and protection by using computer techniques from the direction of improving the sub sea pipeline constructive techniques, expounds in detail the working principles of the software designed in the aspects of the sub sea pipeline＇s stability analysis, the sub sea pipeline＇s arc and span stress analysis, the sub sea pipeline＇s vortex vibration analysis, the sub sea pipeline riser＇s prefabricate and hoisting analysis as well as the assisting action to the sub sea pipeline constructive and protection.Finaly, the rurming procedure and application effect of the software are explained.
