波浪冲滩模型试验采用正态模型还是变态模型. 长时间以来并无定论.本文根所最新资料.提出以正态模型为宜.关于时间比尺,经常采用的是与波周期比尺一致.实则为一种假设,并无理论依据.本文通过两例,说明这种假设井非总是正确,验证试验在当前仍是必不可少的.从该两例来看,按Hallermeier提出的公式推导时间比尺,与试验结果最为接近.
Wave beach model tests using normal model or metamorphosis model. For a long time there is no conclusion. This article is the latest information. Normal model is proposed .As for the time scale, often used is consistent with the wave period scale. But in fact is a hypothesis, there is no theoretical basis.Through two cases, this article shows that this assumption is not always correct, the verification test is still essential in the present.From the two cases, according to Hallermeier proposed formula Time scale, the closest to the test results.
