咸宁市大洲湖为一河道型湖泊,水位涨落会导致湖面面积大幅变化,难以发挥湖泊景观及生态效益,为此,有关部门决定兴建水闸调节大洲湖水文过程. 通过建立河网水动力模型,模拟了大洲湖水闸兴建前后的湖泊水文调蓄过程. 以横沟河建闸方案闸孔孔数的优选为例,详细论述了如何利用河网水动力模型模拟的长系列闸上闸下水位和闸泄流量系列来分析不同闸孔孔数和规模对防洪的影响. 模拟结果表明,9孔方案对防洪影响最小,为最佳规模.

Dazhou Lake in Xianning City, Hubei Province is a river-like one and the water level fluctuation results in the var-iation of the lake surface, so the landscape and ecological benefits can not be fully played. Therefore, the related departments de-cided to construct a sluice dam to control the lake water level. By the established river network hydraulic model, the hydrological process of the lake before and after the construction of the sluice was simulated. Taking the outlets number optimization of sluice built on Henggou River as a case, the influence of sluice outlets number and scale on flood control is analyzed by considering the long-term water level and discharge provided by the established river network hydraulic model. The results show that scheme of 9 sluice outlets is optimal, and its influence on flood control is the smallest.
