摘要
基于三峡水库实测水文、地形资料,采用一维水流数学模型对三峡水库干流动库容进行了计算,在综合分析的基础上对水库各特征段动库容进行了拟合。结果表明,三峡水库干流动库容可通过其与各代表水文站水位的关系来近似简单表达,且具有良好精度;在坝前水位一定的情况下,三峡水库干流的动防洪库容随流量的增大而减小,动、静防洪库容差随着流量的增大而增大。
Based on the measured hydrological and topographic data of the Three Gorges Reservoir,the dynamic reservoir capacity in the mainstream was calculated by a one dimensional numerical model,and the dynamic reservoir capacity of each characteristic reaches was fitted after comprehensive analysis.The study shows that the dynamic reservoir capacity in the mainstream of the Three Gorges Reservoir can be expressed approximately with good accuracy through the water level relationships from representative hydrological stations.In the case of a constant water level in the front of the dam,the dynamic flood control capacity decreases with the increase of discharge,and the difference between dynamic and static flood control capacities increases with the increase of discharge.
