Centerline of plunge pool dam

二道坝中心线

The results show that the vertical-axis eddies near the plunge pool bed are caused by the interaction of the 3-D violent turbulent and boundary conditions;

结果表明：消力池底部的立轴漩涡是由于三维强紊动水流与边界条件联合作用产生的；

Based on a flume experiment, the influence of the curvature change and the jet-trajectory angle change on the transversal diffusion and time-average pressure in the plunge pool are analysed.

基于拱坝表孔泄洪的水槽实验，分析了舌形挑坎曲率和挑角的变化对水流横向扩散及下游水垫塘底板时均压力的影响。
