摘要
为研究三峡水库调峰运行方式对库区支流香溪河水动力特性的影响,建立了非恒定流二维水动力模型。利用该模型计算了三峡水库在双峰调节运行方式下,香溪河的水位、流速、流量变化过程,分析了三峡水库调峰运行时导致的波动性对香溪河流场的影响程度。结果表明:水库调峰运行可以显著增强库区和支流的水位波动,促进水体交换。
In order to analyze the impact of peak load operation of Three Gorges Reservoir to the hydrodynamic characteristics of Xiangxi River, a 2--Dimensional hydrodynamic numerical model was developed. Different hydrodynamic coefficients of Xiangxi River in the double peak load operation mode were simulated by the above model, such as water level, velocity and discharge. The simulated results show that peak regulation can enhance water level fluctuation and water exchange between reservoir area and tributaries.
