目前国内外有关实体消力戽的试验研究文献表明,对于单圆弧式消力戽的下游冲刷规律,尚缺乏足够的系统试验研究.近多年来,国内的一些有关文献,大多是结合实际工程的模型试验对其冲刷规律进行的总结和探讨.作者之一曾就戽唇挑角为45度的情况,进行过系统地试验研究,并就其冲刷规律在文献[1]中做了论述. At present, the experimental research literature about the dissipative force of the entity at home and abroad shows that there is still not enough systematic experimental research on the downstream erosion law of the single-arc dissipative force. In the recent years, some domestic literatures are mostly related to actual engineering The model test of its scouring rules are summarized and discussed.One of the authors once had a lip angle of 45 degrees, conducted a systematic experimental study, and its erosion law in the literature [1] are discussed.
