【摘要】

基于RSS河流数值模拟系统,探讨了平面二维水沙数学模型在涉水工程防洪影响计算中的应用,并以汉江蔡家湾特大桥为例,进行该工程的防洪影响计算,探讨了不同涉水工程的概化方法。结果表明:采用基于非结构网格的平面二维水沙数学模型,可较为准确地捕捉到涉水工程实施前后河道水力要素变化及河道冲淤变化情况;在所选的计算条件下,拟建工程的实施对工程河段的防洪及河势影响不大。

【英文摘要】

On the basis of River Simulation System(RSS),we discussed the application of 2D flow and sediment mathematical model in estimating the influence of water-related project on flood control.Taking Caijiawan Bridge as an example,we carried out analysis of influence on flood control,and discussed different methods of generalizing the water-related projects.The results show that the 2D flow and sediment mathematical model based on unstructured grid can capture the changes of hydraulic factors and silting and scou...
