摘要: 三峡水库区间支流多,入汇流量大,区间入流量及入流过程直接关系到水库调蓄计算的精度,区间入流过程的准确计算是三峡水库水动力学计算中需要考虑的重要问题。针对典型水流过程,利用一维水动力学模型,采用水流水动力逐日演进计算的方法,基于水量平衡原则,反算得到了三峡水库区间日均入流过程,区间入流过程按各支流流域面积比例分配在库区各入汇支流上以加入计算河段,并对区间加水前后的效果进行了分析。结果表明,采用此方法后,三峡水库出库流量过程计算结果与实测结果吻合良好。

Abstract: The Three Gorges Reservoir (TGR) is endowed with many tributaries and large local inflow. The correct calculation of local inflow process is an important issue in the hydrodynamics calculation for the TGR as the amount and process of inflow directly concerns the calculation precision of reservoir regulation and storage. In this article, the daily inflow process in the TGR area is back-calculated on the premise of water balance by a 1-D mathematical unsteady flow model proposed by the author previously. The local inflow process is added to the calculated reach by being distributed to each tributary in correspondence to the proportions of catchment area. The effect of adding local inflow to each reach is analyzed. Results demonstrate that the calculation results of the discharge process of the Three Gorges Reservoir are in good agreement with the measured results after the proposed method is adopted.

Key words: Three Gorges Reservoir, local inflow, mathematical model, back calculation, unsteady flow
