比尺模型上床面切应力研究及应用

Research and application on bed shear stress of scale model

摘要: 用比尺模型研究了湘江洪道刘家坝弯曲型河段的床面切应力，得出了整治工程前后床面切应力的平面分布和阻力沿程的变化。根据试验结果，从河流阻力角度对刘家坝滩整治工程进行了评论。

Abstract: The bed shear stress of Liujiaba meandering river reach are studied by means of the experiment on scale model. The plane and longitudinal distribution of the shear stress is obtained. Based on the test results the Liujiaba shoal regulation engineering is commented.
