河工模型在河流治理开发与保护中的作用

Functions of physical model in river regulation,development and protection

在总结国内外河工模型发展历程的基础上,简要论述了河工模型在大型水利工程建设、河道治理实践、河流开发利用、河流生态保护,以及河口海岸治理与开发利用中的作用,并提出了河工模型试验中需进一步研究解决的模拟关键技术问题,包括河工模型的变态问题、河床阻力相似、模型选沙问题、模型量测技术问题等。

On the basis of summary of development course of physical model at home and abroad,we briefly introduce the functions of physical model in large water conservancy projects,river regulation,river utilization and development,river ecology protection,estuary and sea shore exploitation.We point out the key technical problems which need to be solved in physical model experiment,including distorted models,the similarity of bed resistance,selection of model sediment,measuring and controlling techniques of physical model,etc.
