摘要
本文采用水文、水力学相结合的方法,研究三峡建库后库区洪水波动力特性。首先,通过分析一般河道型水库洪水期水流规律,对三峡建库后库区水流特性进行了预测,其次提出一种水库洪水波模型识别方法,并对三峡工程175方案下百年一遇洪水的洪水波模型进行了研究,最后分析计算了各库段的洪水波波速。本文的结果可供三峡工程的规划设计及可行性论证参考。
In this paper, dynamic characteristics of flood waves in the reservoir region after the completion of the Three-Gorges project are studied by combining hydrology and hydraulic. Firstly, the flow characteristics in the reservoir region are predicted by analysing general regime of flow of river patten reservoir in flood period. Secondly, identification criteria of reservoir flood wave models are presented, and flood routing models are studied when design frequency is equal to 1％ in 175 plan. Finally, celerities of different reservoir reaches are calculated. These results can be used for referencn in the planning, design and feasiblity proof of the Three-Gorges project.
