摘要
底孔冲沙是保障发电洞正常运行的必要措施,研究底沙运动对正确调度底孔有指导意义。通过底沙运动研究,观察湍流现象在泥沙冲刷中发挥的重要作用。
Sand sluicing at bottom outlet is a measure to guarantee the normal operation of power tunnel, so that the research on bed-load movement is of great meaning. By research on bed-load movement, the conclusion that turbulent flow was of important function in sand sluicing was gotten.
