随着社会经济的快速发展，通航水道中的孤礁碍航问题日益突出。采用室内水槽试验和二维水流数学模型对江中孤礁导致其顶部水流条件的变化进行了深入研究。结果表明：孤礁顶部水位跌落值与礁石的长度和高度均密切相关，且呈现出完全相反的相关性；随着孤礁高度的减小，孤礁尺寸对跌水量的影响在逐渐减弱。相关成果可为炸礁工程及通航水位设计提供参考。

With the rapid socio-economic development, navigation obstruction problem is increasingly prominent because of solitary reefs in shallow water. In this paper, the variation of flow conditions at the top of a solitary reef was studied by flume ex-periment and 2D flow mathematical model. The research results show that the drop water has a close relationship with the reef length as well as the height, and they show a completely opposite correlation;with decrease of height of the solitary reefs, the in-fluence of reef size on water drop is weakening gradually. All of this can provide a good reference for underwater reef explosion and navigable stage design.
