摘　　要：通过模型试验，对比研究了在表孔泄洪闸上应用掺气分流墩和在消力池中采用常规消能工的消能效果。对比研究结果表明，分流墩具有一定的消能效果，但对水流条件有特定的要求，有一定的局限性。在调节运行工况变幅较大时，可以采用常规消能工消能。With the model test, the comparative studies of energy dissipation effect of the aeration splitter pier on the surface spillway and the conventional sources on the cushion pool were conducted in this paper. It was shown by the study that aeration splitter pier have certain positive effects, but there is a specific request to the current conditions, so there are some limitations. When the regulation of working conditions varies greatly, the conventional energy dissipation should be used.
