三峡水库香溪河库湾水华水动力调控初步研究
发布时间：2019-02-18 12:25
【摘要】：针对三峡水库蓄水运行后支流库湾春季水华频现问题,利用CE-QUAL-W2模型建立了香溪河-三峡库区整体立面二维水动力数学模型,对三峡水电站不同开机数量和春季不同水文条件下的香溪河库湾流速进行了数值模拟。计算结果表明:香溪河上游来流量较小时,滞留区表层流速小于香溪河库湾水华的临界流速0.05 m/s;而香溪河上游来流量增大到合适的值时,香溪河滞留区表层流速可大于0.05 m/s;仅利用三峡电站小幅度日调节对支流库湾流速的改善效果十分有限,而利用干支流水库对香溪河库湾流速的联合调控效果明显,可控制三峡水库香溪河库湾水华爆发。
[Abstract]:Aiming at the frequent occurrence of Shui Hua, a tributary reservoir bay in spring, a two-dimensional hydrodynamic mathematical model for the whole facade of Xiangxi River and three Gorges Reservoir area is established by using CE-QUAL-W2 model. The numerical simulation of the flow velocity of Xiangxi River Kuwan in the three Gorges Hydropower Station is carried out under different operating quantity and different hydrological conditions in spring. The results show that the surface velocity of the retention area is smaller than that of Shui Hua's critical velocity of 0.05 m / s in the upper reaches of the Xiangxi River. However, when the flow rate of the upper reaches of the Xiangxi River increases to a suitable value, the surface velocity of the retention area of the Xiangxi River can be greater than 0.05 m / s; The effect of the small daily regulation of the three Gorges Power Station on the velocity of the tributaries is very limited, but the combined control effect of the main branch reservoir on the velocity of the Xiangxi River is obvious, which can control the eruption of Shui Hua in the Xiangxi Bay of the three Gorges Reservoir.
