摘要
针对水中悬浮管道,提出其建造方式,并给出计算模型和计算方法。利用Morison公式计算作用在管体上的波浪荷载,计算分析管道在波浪力和水流力作用下的内力。借助ANSYS软件建立水中悬浮管道的有限元计算模型,运用Airy线性波浪理论计算水质点的速度和加速度,在此方法上计算管体的荷载和内力,与公式计算结果进行对比分析。结果表明,两者计算结果基本吻合,其误差在2%范围之内。
The construction method of submerged floating pipeline was proposed and its the calculation model and calculation method were given. The wave loads on the tube were calculated by the Morison formula, and the internal force of the pipeline under the action of wave force and flow force was calcu-lated and analyzed. With the aid of ANSYS software, the finite element calculation model of the sub-merged floating pipeline was established. The speed and acceleration of water quality point were cal-culated by using Airy linear wave theory, the load and internal force on the pipeline were calculated. Comparative results show that the calculation results are basically consistent, and the deviations are within the controllable range, which can provide reference for the subsequent research and applica-tion.
