摘要
通过水槽试验进行了塑料沙的起动流速试验,以5组泥沙为例,推导出沙粒在不同运动状态下塑料沙的起动流速公式,并与3种常用模型沙起动流速公式计算值比较,建议对轻质模型沙起动流速估算时,采用塑料沙起动流速计算公式.
Incipient velocity test of plastic sand is researched by flume experiments.The incipient velocity formula is proposed,varing with the starting states of sediment.It includes the states of single sediment grain beginning to move,a few of sediment starting to move,a lot of sediments starting to move and flapping plastic sand.It is recommended that light weight model sediment incipient velocity is estimated with plastic sand starting velocity formula,constrasted the calculated starting volecity values with the three kinds of commonly used model sediment starting volecity formula.
