| 中文摘要: |
| 本文通过模型试验和理论分析，研究了低水头闸坝工程的泄流能力及其影响因素，特别是闸底板高程与上游河床的相对高差和淹没系数的影响等，得到了不同淹没度情况下低闸枢纽流量或水位的误差计算式和闸底板与上游河床相对高差对流量系数影响的经验公式，经实际工程验证说明了公式的正确性和适用性。 |
| 英文摘要: |
| The discharge capacity and affecting factors of low head sluices, especially the effect of elevation difference between upstream riverbed and sluice project floor as well as the effect of submergence coefficient are studied experimentally and theoretically. The empirical formulas for calculating discharge capacity under various submergences and estimating the influence of elevation difference on discharge coefficient are deduced. The suitability and validity of the proposed formulas are verified by engineering practice. |
