| 摘 要： | 水库蓄水运行后将显著改变库区支流的水动力和水质条件.在这种既定状态,改变枢纽的人控调度方案将产生不同的调度期库区出口断面泄流过程和库水位变动过程,进而产生不同的库区支流水动力条件.水动力条件的改变将对支流水质产生不同影响.基于此,以三峡水库为例,结合实测地形资料构建了三峡库区一维水动力和水质模拟模型,并通过模拟详细探讨了三峡枢纽不同人控调度方案对库区支流水动力和水质的影响.香溪河支流模拟结果表明:三峡枢纽的调峰运行方案和三峡水库的蓄放方案可产生人工潮汐作用和整个支流范围内的干支流水体交换和掺混,提高支流水体流速,对改善支流水环境有利.

| Abstract: | Hydrodynamics and water quality of the tributaries will be noticeably changed after the impoundment of the reservoir.In this situation,different human controlled dispatching solutions will create different flow processes of the outlet section and reservoir water level fluctuation,which will change hydrodynamics of the tributaries.Water quality of the tributary will also be influenced.Based on the above conclusion,one-dimensional hydrodynamic and water quality simulation model of Three-Gorge reservoir was de... |
