| 摘 要： | 机动管线和固定管线不同，是由一根根的管子用连接器或自身阴阳头连接而成。机动管线在水面浮运中所受牵引力的大小是铺设过程中的重要参数。用流速函数描述水面流速分布，得出牵引力的计算公式，并通过Matlab编程分析了任一参数变化时牵引力的变化情况，根据管线自身强度，得出了铺设时的临界点，并对各参数的影响进行了比较，对管线铺设有一定的借鉴意义。

| Abstract: | Mobile pipelines and fixed pipeline are different.The former is composed of a number of tubes connected with the connector or a self-yin and yang connector.The traction it bears when floating on the surface of water is an important parameter in process of pipeline laying.With the velocity function to describe the surface of the water velocity distribution,a traction formula is obtained.The changes of the traction with the variation of any parameter are also analyzed according to its own pipeline strength,so... |
