摘要
在文献[1]的基础之上,本文提出了在轴向力作用下海底油气管道的计算模型。根据共振条件,讨论受轴向力作用之海底油气管道的极限冲刷长度的计算问题。借助于加权残数法使问题得以求解。文末用算例说明其有关计算过程,并对影响海底管道冲刷长度的主要因素进行了分析讨论。
Based on the reference (1).this paper puts forward the calculating model of the oil and gas submarine pipelines acted by the axial force.
The calculation of the limit erosion length of the oil and gas submarine pipelines is discussed according to the resonance condition under the axial force. The solution of the question is obtained by means of the weighted residual method. An example is given to show the calculation in the end. The analysis and discussion of the main factor are also carried out that affects the limit erosion length of the oil and gas submarine pipelines.
