西藏拉洛水利枢纽工程位于西藏自治区南部日喀则地区. 德罗电站前池溢流堰采用开敞式平底宽顶堰,沿山脊布置下游泄槽,最大落差达230余米,泄槽底坡变化大、线路曲折,全长2 297. 20 m. 针对泄槽复杂多变的弯道及坡度的水力设计难点,设计提出泄槽采用沿程设置台阶、中部间隔加设整流池及末端设置消力池的综合解决方案,有效地适应了弯道、底坡变化大的自然条件,且成功解决了高水头、高速水流的消能难题.其工程经验可供同类工程参考.
西藏拉洛水利樞紐工程位于西藏自治區南部日喀則地區. 德囉電站前池溢流堰採用開敞式平底寬頂堰,沿山脊佈置下遊洩槽,最大落差達230餘米,洩槽底坡變化大、線路麯摺,全長2 297. 20 m. 針對洩槽複雜多變的彎道及坡度的水力設計難點,設計提齣洩槽採用沿程設置檯階、中部間隔加設整流池及末耑設置消力池的綜閤解決方案,有效地適應瞭彎道、底坡變化大的自然條件,且成功解決瞭高水頭、高速水流的消能難題.其工程經驗可供同類工程參攷.

Laluo Hydro-junction is located in Xigaze region of southern Tibet. The open flat-bottom broad crest weir was a-dopted as the overflow weir of the fore-bay of its Deluo Hydropower Plant and the discharge spillway with full length of 2297.20 m in the downstream is constructed along a slope-varied, tortuous mountain ridge with the largest fall of more than 230 m. Ai-ming at the difficulties in hydraulic design such as the complicated and varied bend and slope of the discharge spillway, the solu-tion is put forward, which sets steps along the spillway, space interval regulating poll in the middle section and silting basin at the end of the discharge spillway. It suits the natural conditions of varying bend and slope and solves the difficulties of energy dissipa-tion of high-head and high-speed flow.
