本文对金属管道的弯矩能力进行了研究，为优化管道海底干预设计的成本效益提供标准。导出了管道在压力、纵向力和弯曲联合作用下的极限承载能力的解析解，并与有限元法获得的结果进行了彻底的比较。导出的方程可用于具有各向同性和各向异性应力/应变特性的高强度材料，如果根据适当的目标安全水平校准安全系数，则可应用于管道、立管和管道。[S0892-7219(00)00504-5]
In this paper, the bending moment capacity for metallic pipes has been investigated to provide criteria for optimizing the cost effectiveness in pipeline seabed intervention design. An analytical solution for the ultimate load-carrying capacity of pipes subjected to combined pressure, longitudinal force, and bending has been derived and thoroughly compared against results obtained by the finite element method. The derived equations can be used for high-strength materials with isotropic as well as anisotropic stress/strain characteristics, and may be applied for pipelines, risers, and piping if safety factors are calibrated in accordance with appropriate target safety levels.[S0892-7219(00)00504-5]
