钱塘江九溪涌潮物理模型试验研究

Experimental Research on Physical Model of Tidal Bore at Jiuxi Reach of the Qiantang River

针对钱塘江九溪岸段特殊的涌潮现象,建立涌潮物理模型,模拟河段涌潮的形成与传播过程,观测分析涌潮传播过程的水位壅高、越堤水量等。研究表明,建立的物理模型反映九溪河段涌潮基本特征,为该河段后续治理工作中的涌潮保护、工程防护与减灾研究奠定基础。

Aiming at the special tidal bore phenomenon at Jiuxi reach of the Qiantang River,a physical model of tidal bore is established to simulate the tidal bore formation and propagation,in order to monitor and analyze its maximum run-up height and water volume over embankment.The study shows that the physical model reflects the basic characteristics of the tidal bore in Jiuxi reach,which lays a foundation for the future study of tidal bore protection and disaster reduction in the river regulation project.This paper has reference significance for the study of tidal bore,engineering protection and disaster reduction in other reaches of the Qiantang River.
