取計(jì)算時(shí)段△t=12h。,,假定洪水到來(lái)時(shí)，水位剛好保持在溢洪道堰頂，即起調(diào)水位為65m,,,,,,,,,

（1）繪制Z-V曲線按表1所給的數(shù)據(jù)，繪制庫(kù)容曲線Z-V(圖1),,,,,,,,,,,

（2）列表計(jì)算q-V曲線在堰頂高程65m之上，假設(shè)不同庫(kù)水位Z列于表3中，用它們分別減去堰頂高程65m，得到堰頂水頭H,,,,,,,,,,,

q堰=m1*B*H3/2=1.6*30*H3/2=48H3/2從而算出各H相應(yīng)的溢洪道泄流能力，加上發(fā)電流量6m3/s，得Z值相應(yīng)的水庫(kù)泄流能力q=q堰+q電,,,,,,,,,,,

列于表3（3）中，再由（1）的Z值查圖Z-V曲線，得Z值相應(yīng)的庫(kù)容V，列于表3（4）中。,,,,,,,,,,,
