葫芦湾枢纽泄水闸泄流能力研究

Study on discharge capacity of Huluwan hydro-junction release sluice

基于相关资料,通过断面模型试验研究了葫芦湾枢纽设计中的单孔泄水闸泄流能力问题,发现枢纽原设计方案试验中,在洪水期水闸单孔泄流能力不能满足要求。通过分析该水闸泄洪时的水力特性,采取降低闸底板高程的措施有效地解决了问题,优化了泄水闸结构设计,并通过试验描绘出单孔水闸的泄流曲线,为枢纽建设提供了必要的技术支撑。

Based on relevant data, the discharge capacity of single sluice in Huluwan hydro-junction design was analyzed according to the sectional model test, then it was found out that the single sluice discharge capacity of original design scheme can not satisfy the requirement during the flood period.Through analyzing the hydraulic characteristic during flood discharge ,the problem was effectively solved by reducing the elevation for bottom board of the sluice gate, the sluice structural design was also optimized in this paper, and the discharge curve of the single sluice was obtained by experiment.
