利用激光测速仪首次对悬板分层水流流场特性进行了测试研究，并分析了其对输沙过程的影响，得出以下结论：（1）设置悬板不仅能引取表面清水，而且加大了悬板下冲沙廊道内的纵向流速，有利于排除来流中的推移质泥沙；（2）不同的悬板头部体型对流场的水流结构有明显的影响，相对于流线型头部体型来说，皮氏堰头部体型能加大廊道内的纵向流速，有利于冲沙，不足之处是过堰水流流速较大，易于产生冲击波；（3）在满足工程布置要求的条件下，悬板长度应尽量缩短为宜．
The laser velocity meter for the first time on the flow characteristics of the stratified flow field of the suspension plate was studied and analyzed its impact on the sediment transport process, the following conclusions: (1) the installation of suspended panels can not only bring the surface water, but also increase The longitudinal flow velocity in the corridor under the suspended board is conducive to the removal of the pushed sediment in the incoming stream; (2) The body shape of the different suspension board has a significant effect on the flow structure of the flow field. Compared with the streamlined head Body shape, Pittsburgh head body shape can increase the longitudinal flow velocity within the corridor, is conducive to flushing, the downside is the weir flow velocity is large, prone to shock wave; (3) to meet the requirements of the project layout conditions , The length of the suspension board should be shortened as appropriate.
