  1. In the suspended sediment transport model, the method of shear stress is adopted to determine the source function in the suspended sediment diffusion equation. through a series numerical experiments and statistical analyses of observed field data, a local coefficient, which can reflect the bottom material and consolidation, is introduced into the classic critical erosion velocity of the sediment

    懸沙輸運模型利用切應力方法來確定對流擴散方程中的泥沙源函數,其中的臨界起動速度利用經典的泥沙起動流速公式前面增加一個局地系數得到,這個系數能反映河床底質結構及固結程度,通過系列數值試驗和實測資料的統計分析確定。
  2. In this paper a date from some real projects are used to analyse the facors that will affect the energy dissipation and erosion prevention. such as flood discharge across the cofferdam, crest elevation, downriver cofferdam, roughness coefficient and the gradient of the surface of dam, and so on. in this paper, the program based on hydraulics is checkout by the tankeng waterpower project in zhejiang. the results prove that this program can be used to design any project where there is no obvious side shrinking phenomena

    本文結合工程實際對影響圍堰和壩體消能防沖的各種因素,包括過堰流量、壩面高程、下游圍堰堰頂高程、壩面糙率、壩面坡度等進行了分析,並藉助水力學知識和計算機語言編寫了圍堰和壩體的優化計算程序,並利用浙江灘坑水電站工程對所提出優化計算程序進行了驗證,證明了該程序在沒有明顯的側收縮的影響下,計算結果與實際情況較為吻合。
