摘　　要：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。This article describes the design features of the physical model of salt tide in Modaomen estuary, including the determination of the model boundary, the selection of the model scale, the design of the backwater and water supply system. The model validation test has been conducted, and the analysis has been done on the velocity at the verification point, the salinity vertical distribution and the similarity between the fortnightly tide and the prototype. The verification results show that the model agrees well with the prototype, the model design is rational, and the test methods are feasible. The model can be applied to the related salt tide research trials, and the model design and verification experience can be reference to similar tests in China.
