河床变形混交模型预测技术及其进展

Prediction of Riverbed Deformation Mixed-Model and Its Development

把河工模型试验和数值模拟计算两种手段有机结合 ,研究同一河段的泥沙问题 ,称之为河床变形混交模型预测方法 .提出并行混交、连接混交和内插混交三种类型 ,人工耦合、半自动耦合和自动耦合三种混交方式 ,以及广义混交模型的概念 .

Combining model test with numerical simulation to study sediment problems is called the mixed model method for the prediction of riverbed deformation. Introduced are three kinds of mixed model: the parallel mixed model, the linking mixed model, and the inserting mixed model, and three coupling ways, i.e. the artificial coupling, the semi automatic coupling, and the automatic coupling. The concept of generalized mixed model is also presented. Finally, the present situation and development tendency of the mixed model are discussed.
