HYDRAULIC RESEARCH ON THE LAYOUT OF VERTICAL SLOTFISHWAY IN NEW SHANGZHUANG GATE

摘要

During the reconstruction of Shangzhuang Gate in Beijing, an ecological fishway, whichrnacts as an ecologic flow passage and fishway, is suggested and designed at right bank of the newrngate to rehabilitate zoology and protect the biology diversification. Referring to the practicalrnexperiences of other fishways at home and abroad, the vertical slot fishway which is one of thernmost popular style of fishway in the world nowadays is adopted for new Shangzhuang Gate. In thisrnpaper, by the use of hydraulic model test with a scale of 2.5, the hydraulic parameters of verticalrnslot fishway are optimized, and the layout of fishway with deflecting block presented here has beenrnused in engineering.
