摘　　要：抽水蓄能电站进水口的吸气漩涡对水利水电工程有很大的危害,例如:使得泄流能力减小、水力机械效率降低,产生振动和噪音。进水口漩涡可以通过改善进水口水流边界条件,修建专门的建筑物如消涡梁等方式予与消除。文中结合某抽水蓄能电站的水力学试验,探讨了三种消涡梁的消涡效果。对单层消涡梁,提出了消涡梁布置与旋涡强度之间的关系。可供类似工程参考和借鉴。Inspiration eddy at the intake of pumped storaged power station does a great harm to the project by decreasing the flood discharge capacity and the hydraulic mechanical efficiency, as well as causing vibration and noises. It is possible to eliminate the eddy by improving the flow boundary condition at the intake with special structures such as eddy-eliminating beam. By taking the hydraulic examination done in a pumped storaged power station as an example, this paper discussed the eddy-eliminating effect of three kinds of eddy-eliminating beams, and the relations between the arrangement of beams and the eddy strength is also put forward for reference of similar projects.
