By the hydraulic model test the application feasibility of the roller bucket with low - ridge was demonstrated . comparing the hydraulic calculation data and operation rusultes , the article made some summarise . the principle of mixed flow for energy dissipation design has been well vertified through the study results 本文主要通過對某電站水利樞紐下游消能防沖的水力計算和整體模型、斷面模型的試驗分析,驗證了低鼻坎戽流消能在此類工程中應(yīng)用的可行性。
The projects on the downstream of river are increasing recently . the common features of these projects are low head , low frounde number , large discharge ect . the roller bucket with low - ridge is applicated on the project for energy dissipation in the condition of low fr current and low head 目前修建在河流中下游的水利樞紐工程日益增多,此類河流的泄洪消能有共同特點,即低水頭、單寬流量大,考慮上游淹沒、移民、河道兩側(cè)的交通等問題,不宜抬高河道水位,往往采用低堰泄流。
