结合乌江构皮滩水利枢纽工程消能问题研究,用热膜流速仪在比尺为1∶380的精细模型上量 测了拱坝挑跌流在水垫塘内的流速场,并由试验成果分析了淹没射流在水垫塘内的消能过程, 计算了消能率。研究表明,要想提高水垫塘的消能效率,就必须设法增大强紊动剪切层区的范 围。 

 Through study on energy dissipation of Goupitang Project on the Wujiang River ,the velocity field in the water cushion pool downstream skijump or drop was m e asured by hotfilm anemometers on a fine model with scale 1∶380. The energy di ssipation process in the water cushion pool was analysed using experimental res ults,and the rate of energy dissipation was calculated.The study showed tha t if a project requires to raise its rate of energy dissipation,the strong turbulent shear flow region must be extended. 
