摘要: 根据标准“DNVGL-ST-F101海底管道系统”，可以假定当混凝土配重层应变达到(−) 0.2%时，混凝土发生破碎。本文建立了含混凝土配重层的海底管道三维模型并基于以上假设建立了边界条件，利用ANSYS软件对三种不同混凝土壁厚管道的许用弯矩进行了数值模拟分析。分析结果对于指导海底管道铺设施工具有指导作用。
Abstract: As per standard “DNVGL-ST-F101 submarine pipeline systems”, it can be presumed that when the concrete weight coating strain reaches (−) 0.2%, the concrete crushing occurs. This paper establishes the 3D model of offshore pipeline with concrete weight coating and based on the above-mentioned assumption builds the boundary condition. Numerical Simulation Analysis was carried out for the determination of the allowable bending moments of pipe joints with three different concrete thicknesses by using software ANSYS. The analysis results have some guidance for the offshore pipeline laying construction.
