南山工程冲淤试验模型沙选择研究

Model Sand Selection Research about Scouring and Depositing Tests of the Nanshan Engineering

在泥沙模型的相似条件中,泥沙运动相似是一个极为重要的条件,其中模型沙与原型沙的起动相似、沉降相似是保证泥沙运动相似的具体条件。结合南山工程冲淤试验,根据波浪作用下的泥沙起动相似,进行了模型沙选择分析和实验验证,对波浪作用下的泥沙模型试验设计具有指导意义。

In similar conditions of sediment models, the sediment movement similar conditions are very important conditions. Among them, the incipient and settlement similar conditions of the model sand and the prototype sand are required. In this paper, the Nanshan engineering scouring and depositing tests are combined with. According to the sediment incipient similar condition of the wave action, the model sand choice analysis and experimental verification are carried out. The study has reference significance on similar model test designs.
