摘要
如何准确又简便地模拟城市建筑群是溃坝洪水演进计算所关注的问题之一。提出用"等效糙率"模拟建筑群的方法及"等效糙率"取值的水槽试验手段,并成功应用在某城市水库溃坝洪水演进研究中。
How to simulate the urban building group in a simple and accurate way is one of the major problems in the dam-break flood flow evolution calculation. The equivalent roughness simulation method and the relevant flume experiment based on the equivalent roughness value, which has been proved successful in a certain dam-break flood flow evolution study, is presented in this paper.
