中文摘要 | 本研究經以公式推導知,目前水土保持手冊使用之防砂壩梯形溢流口流量公式乃梯形銳緣堰公式,不僅與理論不合,而且,其所估算之水頭高度會較小,安全性較低。經過渠槽試驗之驗証,在本研究之試驗條件下,流量公式建議為梯形寬頂堰公式乘上一流量修正係數: Q=0.7(0.5+1.5/1+2myс)□ (1+myс)□ Where, yc=-(3-4mh)+□/10m m=z/b |
英文摘要 | This study, by process of deriving formula, understood that the discharge formula on trapezoidal spillway of sabo dam used by Handbook of Soil and Water Conservation nowadays was trapezoidal thin-plate weir formula. This selection not only was unsuitable to theoretical work but got smaller water head resulting in lower security. After the verification of flume experiment associated with experimental conditions of this study, discharge formula would be suggested as trapezoidal broadcrested weir formula multiplied by correction coefficient. Q=0.7(0.5+1.5/1+2myс)□ (1+myс)□ Where, yc=-(3-4mh)+□/10m m=z/b |
