通过水槽试验,结合理论分析,研究丁坝附近水流紊动强度沿水流方向、水深方向和横向的分布规律。绘制5种不同坝体结构形式其周围水流脉动动能和紊动强度的分布等值线图并分析分布规律,进一步探讨不同坝体挑角对丁坝附近水流紊动强度和脉动动能的影响。

英文摘要：

This paper studies the distribution laws of flow intensity along the flow direction, the depth direction and the transverse direction based on the flume experiments and theoretical analysis, drafting the contour maps of the flow turbulence intensity and turbulent kinetic energy of the five different types of dam structures and distribution laws. Furthermore, the effect of different dam angles on the flow turbulence intensity and turbulent kinetic energy is also explored.
