摘要
建立了S型深海管线铺设系统管线悬空段的控制方程,应用奇异摄动方法对方程进行了求解,并采用解析和数值相结合的方法进一步分析了管线水下重力、张紧器张紧力等参数对管线形态的影响。分析结果有助于深入了解大深度管线铺设中的力学行为,并可进一步为深海管线、缆索铺设施工设计提供理论依据。
The equation which governs pipeline S-laying in deep sea was established and solved by singular perturbation technique. Effects of pipeline weight underwater and tension of tensioner on static configuration were further analyzed with the aid of hybrid analytical and numerical method. The present work helps to understand the mechanics of pipe and cable laying in deep sea,and thus provides references for engineering design.
