摘要
本文首先扼要介绍了国内外研究冲刷漏斗稳定形态与趋孔水流运动特性的现状,接着归纳了冲刷漏斗稳定形态的基本特征,详细陈述了笔者对趋孔水流运动的试验方法、观测手段和试验结果,得出了趋孔水流的流速分布特性,并据此解释了冲刷漏斗的形成与稳定原因。
This paper at first briefly introduces the up-to-date research results about topographies of scouring funnels and flow movement in front of an intake and concludes the primary characteristics of scouring funnels, then the method of the flow velocity measurement-and experimentary results have been described detailly. The specifications of the flow velocity distribution have been gotten, and the deformative and steady causes of scouring funnels havre been discussed in the last of this paper.
