确定海底埋设输油管线允限冲刷长度的一种实用方法

A Practical method of Obtaining Allowable Erosion Length of Sea-Bottom Imbeded Oil Pipeline

本文根据梁的强度理论提出了确定海底埋设输油管线冲刷长度许用值的一种方法—弯矩修正法，并给出了算例。算例表明该方法计算简单、结果可靠，不失为一种工程实用方法。

In this paper,on the basis of beam strength theorythe author presents the modifying-moment method,by which allowable erosion length of a sea-bottom imbeded oil pipeline can be obtained easily.The example in the paper shows that the calculation is simple and the result is reliable.Thus the method is practical in engineering.
