摘要
本文通过对三门峡双层泄水孔原型噪声观测资料的分析,澄清了在水工模型试验中未能取得一致意见的若干水力学问题,所得成果对确定三门峡双层泄水孔的改建方案有重要的现实意义。
By analyzing the prototype observation data for the double layer outlets of Sanmenxia dam, in this paper, the following hydraulic problems found through hydraulic model tests, on which identical agreements was not reached, were clarified: what is the nature of the bow-shape vortex band within the inlet inclined gate slot; if the cavitation in the top corner area can be eliminated or not after the modification of the inclined gate slot; if cavitation problems is in existence at the position of connection well. The results have practice significance on the schedule of the modification of the outlets.
