摘要
在复式断面明渠中，由于存在滩槽水流动量的交换，改变了边界剪切应力的分布规律，进而影响滩槽的阻力和输水能力。本文利用作者实测的剪切应力分布资料，通过与矩形明渠边界剪切应力分布的对比，对复式断面边界剪切应力分布的特征进行了分析，建立了滩槽平均边界剪切应力与水深的关系。
Compared with single channel,distributions of boundary shear stress are changed by the momentum transfer between main channel and floodplains.So,the frictional resistance and the sediment carrying capacity of flow are also changed for the main channel and floodplains.Some characteristics of shear stress are analyzed by the experiment data,and some relations between relative depth and average shear stress are obtained.
