本文从设计角度,讨论了缓变流和一般变速流方程式对大比降陡槽的适用问题,经过大量计算数据的分析、建立和应用一个陡槽直接因子参数П,提出大比降陡槽净水深的计算公式,并与十六个模型试验成果相对照,取得一致。进而应用陡槽直接因子参数П_c,根据国内外十二项工程原型观测资料,得到大比降陡槽掺气水深的计算公式。从而使大比降陡坡设计中,陡槽水深这一主要问题在目前有一较为合理的设计方法。
In this paper, from the design point of view, we discuss the application of slow flow and general variable flow equations to large-ratio chute. After a large amount of calculation data analysis, we establish and apply a direct factor of chute П, Depth of the formula, and with the results of sixteen model tests in contrast to achieve the same. Further, the direct factor of slope factor П_c is used to calculate the aeration depth of the steep slope based on the observation data of 12 engineering prototypes at home and abroad. So steep slope design, steep deep water depth of the main problem at the moment there is a more reasonable design.
