2、才公式，改寫后得，此式與達(dá)西魏斯巴赫公式，可得，可推出短管自由出流式中,水位高程大于溢洪道堰頂高程，所以要進(jìn)行隧洞和溢洪道聯(lián)合泄流計(jì)算。隧洞和溢洪道聯(lián)合泄流計(jì)算短管自由出流隧洞下游底板高程，則實(shí)用堰的下泄流量為實(shí)用堰的普遍公式經(jīng)過試算得0.882，查圖取0.995，m取設(shè)計(jì)值0.502，則,壩體攔洪高程設(shè)計(jì)水位與下泄流量關(guān)系表淹沒系數(shù)側(cè)收縮系數(shù)流量系數(shù)m溢流寬度B水位高程H溢洪道下泄流量隧洞下泄流量總下泄流量Q0.9950.998 0.502 80102.415.80 420.61 436.41 0.9950.988 0.502 80103.4229.98 420.61 650.59 0.99
