摘要: 魚道進(jìn)口布置受多種因素影響,當(dāng)下游河道水位變幅較大且魚道進(jìn)口數(shù)量布置受限時(shí),魚道進(jìn)口難以承受較大水位變幅,誘魚水流條件差。為此,提出了設(shè)置流速調(diào)節(jié)浮箱對(duì)魚道進(jìn)口結(jié)構(gòu)進(jìn)行優(yōu)化設(shè)計(jì),并采用三維數(shù)值模擬對(duì)魚道進(jìn)口流速調(diào)節(jié)浮箱布置進(jìn)行了優(yōu)化研究。研究結(jié)果表明:魚道進(jìn)口段浮箱尺寸確定與下游水位變化密切相關(guān),魚道進(jìn)口布置適當(dāng)高度的浮箱,可以明顯改善進(jìn)口區(qū)域的流速條件;浮箱長(zhǎng)度和魚道進(jìn)口段長(zhǎng)...
