以某低水头航电枢纽水工模型试验为基础，进行了遥控自航船模试验，分析了施工导流阶段围堰引起的横流对船模航行的影响。结果表明，斜流对船模航行的影响程度主要与横向流速大小、区域及船体的对岸航速有关。该研究方法可以为航道水力学研究和航道工程设计提供参考。

On the basis of the river physical model test of some low-head navigation and hydropower project ,the test of a remote-control self-propelled model ship was carried out, the influence of cross-flow caused by the construction cofferdam on the ship model has been analyzed. The results show that the degree of influence of cross-flow on ship model sailing mainly is related to the region and size of the cross-flow as well as the ship model sailing velocity to the bank. Research methods can provide a reference for hydraulics research and waterway engineering design.
