摘要
为了加强学生对泥沙起动相关理论的学习和理解,特设计出适用于本科教学的"波流作用下泥沙起动实验"。通过观察泥沙起动现象、测量泥沙起动流速、分析对比实验数据,使学生全面掌握波流作用下泥沙的起动、床面变形和泥沙输移问题。该实验的教学应用,有效激发了学生的学习兴趣,培养了学生严谨的科研作风,提高了学生分析问题和解决问题的能力。
It is also the basic content of river dynamics and sediment movement. It is necessary to design an experiment to improve the students’ comprehension about the theory of river dynamics. In this experiment , students can observe the phenomenon of sediment motion ,measure the threshold velocity of sediment particles as well as analyze the experimental data. From this ,the learning interest and the ability of analyzing and solving problems should be improved.
