摘要
埋地管线穿河段由于河水冲刷而悬空，在水流作用下诱发涡激振动。本文在实测悬空管线固有频率的基础上，提出了其固有频率的计算方法。按本文方法所得结果和实测结果基本吻合。
Vortex-vibrations of suspended pipelines crossing rivers with flushing induced by fluid often take place. This paper,based on the results from measuring, Presents the calculation method of natural freguencies. The results of this paper are in agreement with the measured results.
