三峽水庫(kù)香溪河庫(kù)灣水華水動(dòng)力調(diào)控初步研究
[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.
