摘    要:
对多种轻质模型沙的物理化学特性及起动特性进行了研究.研究结果表明,在模型沙林料中,煤粉和煤灰相对而言性能比较稳定,特别是粉煤灰成本低,易加工,可动性强,是模拟黄河下游游荡性河道的理想模型沙.通过试验研究还发现,轻质模型沙起动规律一致,一般可表示为V0=kdHa形式.

关 键 词:轻质模型沙  特性  起动流速

Abstract:
Through experiment,the different light model sediment moving low and character of physical and chemical can be studied.Among there the coal powder and cindery coal are better model sediment,and it is applicable to study Yellow River low reach riverbed evolvement.Light model sediment moving law are similitude,it can be expressed as V0 =kdH^a.
Keywords:light model sediment  characteristic  pick-up velocity
