摘要
针对大梁水库放水洞多级孔板消能问题，分析了多级孔板消能中孔径比、上游水位及出口面积对水流空化数的影响。在此基础上给出了多级孔板布置的设计方法并在大梁水库放水洞试验中进行了应用。实践表明，该方法能给出较为合理而实用的布置方案。
According to the issues of multi-stage orifice dissipation of the sluice tunnel of Daliang Reservoir. the paper analyses the effects of diameter ratio of orifice, upstream level and outlet area on cavitution in multistage orifice dissipation. It puts forward a design method for the layout of multi-sarge orifices and is applied to the sluice tunnel of Daliang Reservoir. It is shown through the practice that the method is reasonable and workable.
