摘　　要：宽尾墩是行之有效的收缩式消能工体形,也经许多工程实践所证实。它消能效果和流态很大程度取决于体形设计。本文简要的论述几个体形参数的选择,同时也讨论了宽尾墩泄洪时雾化问题,并提出雾化影响计算公式和雾化防治观点。Flaring gate pier dissipator is advantageous for energy dissipation in engineering practice. The effect on energy dissipation and atomization is significantly depended on its shape. Usually, the better is the energy dissipation effect, the more serious is the effect of atomization. So it is difficult to balance the atomization effect against energy dissipation. Some characteristics of flaring gate pier shape is discussed briefly on the effect of atomization in this paper. A forecast formula for the atomization range is developed. Several protective measures are suggested to mitigate the effect of atomization caused by the flood discharge flow.
