  1. Abstract : 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 measured by hot - film anemometers on a fine model with scale 1 380

    文摘:結合烏江構皮灘水利樞紐工程消能問題研究，用熱膜流速儀在比尺為1 380的精細模型上量測了拱壩挑跌流在水墊塘內的流速場，並由試驗成果分析了淹沒射流在水墊塘內的消能過程，計算了消能率。
  2. But the general used ski - jump energy dissipation scheme often causes a series of insurmountable difficulties, such as fogging, cavitations demolition, and bank scouring

    而常規的挑流消能方案，又常出現象霧化、空蝕破壞、岸坡沖刷等較難以克服的問題。
  3. The trajectory bucket is improved and optimized for suitable trajectory distance and small scouring

    泄洪洞挑流坎挑流消能時，當泄流量較小時，挑距較短。
  4. For a single plunging jet, two optimization models are respectively introduced according to the jet trajectory distance and the depth of scour pool, and the optimal computation of the jet trajectory distance in xiao - wan project demonstrates that these models are reasonable ; 5

    對于單股挑流消能水舌，以挑距和沖坑深度為控制目標，分別首次建立了優化數學模型，並通過對小灣拱壩單孔挑流水舌的計算，說明所提出的數學優化模型是可用的； 5
  5. For two up and down plunging jets, an optimization model is introduced according to maximum energy dissipation. in this model, the exit angle of jet is first considered actually. the optimal computation of the energy dissipation between two impinging jets in xiao - wan project demonstrates that this model is reasonable too ; 6

    對于上、下雙股挑流水舌，以碰撞消能率為優化目標，首次考慮了出口水舌的坦化影響因素，建立了優化數學模型，並通過對小灣拱壩壩身表、中孔水舌的碰撞計算，認為所提出的數學優化模型是可用的； 6
  6. In order to increase the energy dissipation of stepped spillway at iarge unit discharge, the integhty dissipater of aerated splitter pier and steppe characteristics is studied. because of verticaj diffhaion now by aerated splitter and impachng steppe 3 by drop flow, the air concentration and the energy dissipation efficiency are greatly increased ; the potentiality of cavitations is decrease. in special at large unit discharge, this effect is more obvious

    摻氣分流墩的增加，明顯地改善了階梯面上的壓強分佈，消除或減小了階梯凹角內和立面上部的負壓；由於摻氣分流墩使水流縱向擴散以及挑流落下后在階梯上的撞擊，使水流的摻氣濃度和消能率都得到較大的提高，降低了階梯面空蝕的可能性，特別是在大單寬流量時，這種效果更為明顯。
