介绍了磨刀门河口咸潮物理模型的设计要点,包括模型边界的确定、模型比尺的选取、模型供回水系统的设计等,并开展了模型验证试验,对验证点的流速、盐度垂线分布及其半月潮过程与原型相似程度进行了分析。验证结果表明:模型成果与原型吻合较好,模型设计合理,试验方法可行,模型可以开展相关咸潮研究试验,其模型设计与验证经验可供国内开展类似试验研究参考。 The design essentials of saltwater physical model of Modaomen estuary are introduced, including the determination of model boundary, the selection of model scale and the design of model water supply and return system. The model verification test is carried out. The flow rate, salinity The vertical distribution and the similarity between the half moon tide process and the prototype are analyzed. The results of the verification show that the results of the model are in good agreement with the prototype, the model is reasonable and the test method is feasible. The model can carry out the research on the salinity tide, and the model design and verification experience can be used for reference for similar experiments in China.
