摘要
为检验三峡水库变动回水区泥沙实体模型试验研究成果的精度,根据已建丹江口水库原型观测资料和丹江口水库变动回水区库段实体模型泥沙冲淤试验成果的对比、分析研究了泥沙实体模型的相似性,对影响模型相似性的关键因素进行了探讨。研究表明,三峡水库变动回水区泥沙实体模型相似性也是较高的,模型能够预报较长期的河流泥沙冲淤和河床演变情况,试验研究成果可信。
In order to verify the accuracy of the experimental result gained from the sedimentation model tot the fluctuating backwater region of the three Gorges Reservoir, a comparative study was made between the data observed from the prototype, the existing Danjiangkou Reservoir, and the results obtained from the experiment on erosion and deposition on the model for the fluctuating backwater region of the same reservoir, and a research on the similarity of the sediment model and the key factors affecting such similarity was similtaneously conducted. The research indicates that the similarity of the model of the fluctuating backwater region of the Three Gorges Reservoir is comparatively high and that the model will be able to predict, for a relatively long term, the condition of the erosion and the deposition and the evolution of the river bed, and that the results obtained from the experiment and ??research are credible.
