摘要
珠江河口是世界上最复杂的河口之一,进行整体水流模拟是比较困难的。介绍了自行开发的珠江河网河口湾一、二维联解整体潮流数学模型及大范围整体潮汐物理模型,两种技术手段相辅相成,较好地解决了该河口潮流运动的整体模拟问题。以特大型跨河口工程——港珠澳大桥为例,介绍了两种模型的应用情况,在数学模型中引入通度系数控制工程复杂边界过流量,取得了较好的模拟效果。
The Pearl River Estuary is one of the world＇s most complex estuaries and the overall flow simulation is more difficult. This paper describes the development of the Pearl River River estuary, the overall trend of a 2-D coupled mathematical model, and large overall tidal model. The two technologies complement each other and better solves the whole estuarine tidal motion simulation problems. Taking the untra-large river-crossing engineering, the Hong Kong-Zhuhai-Macao Bridge for example, this paper introduces the application of the two models. Introducing the aperture coefficient to control the engineering of complex boundary flow in the mathematical model, we achieve a good simulation effect.
