摘要
基于剪滞理论提出了海底双层管线热膨胀分析计算的新方法。该方法不仅具备工程常用方法的计算功能,而且可以计算得到双层管线轴向力的分布状态以及土壤摩擦力对管线轴向力的影响规律。本文提出的计算方法简单、方便,获得的结果直观、详细,可以用于分析海底双层管线的热膨胀问题。
A new thermal expansion calculation and a nalysis method for submarine pipe-in-pipe is proposed based on the shear lag theory. The method not only has the calculation function of commonly used engi neering methods, but also can obtain the axial force distribution of submarine pipe-in-pipe and the effect of soil friction on axial force of pipe-in pipe. The calcula- tion method is simple and convenient with visual and detailed results, and can be used for the thernml ex pansion analysis of submarine pipe-in-pipe.
