摘要
利用非线性管道变形和应力数值计算模型,对大直径薄壁管道进行空间形态和应力分布模拟计算,分析实际铺设作业中的横向和侧向水流对管道空间形态和应力分布的影响,并根据数值计算的结果总结横向水流和侧向水流的作用效果,提出管道铺设工程中应该注意的问题。
The paper uses the numerical model to analyse the form and stress condition of pipe laying in the typical field considering the lateral current. From the result of numerical simulation, some conclusions have been gained about the influence by lateral current; suggestions are also made for pipe laying.
