摘要
本文以自主研发并经过实测资料验证的三峡水库一维非恒定流水沙数学模型为基础,将溪洛渡及向家坝水库纳入整体计算范围,建立了包括溪洛渡、向家坝和三峡三个水库的长江上游梯级水库联合调度一维非恒定流水沙数学模型。本模型为一基于树状河网的全沙模型,可将溪洛渡水库库尾—三峡坝址的长江干流和部分主要支流作为一个整体进行泥沙冲淤同步联合计算,采用该模型对水库群联合运用条件下各水库泥沙冲淤变化及相互影响进行了研究,初步揭示了长江上游特大型梯级水库群泥沙淤积规律。
This paper presents a 1-D mathematical model of unsteady flow and sediment transport for joint operation of cascade reservoirs in the upper Yangtze that is an extension of the similar model previously developed for the Three Gorges reservoir（TGR） and verified with the field measurements.This new model covers two new reservoirs,Xiluodu reservoir and Xiangjiaba reservoir.It is a total sediment model for erosion and deposition suitable for tree-type river networks,and the system components,such as the Xiluodu-TGR mainstream of the Yangtze and its main tributaries,can be calculated jointly and synchronously.It was used to study the interaction of sedimentation events in these reservoirs operated jointly by the cascade reservoirs rule,and the results revealed preliminarily the sedimentation natures of large-scale cascade reservoirs in the upper Yangtze.
