摘　　要：本文研究了细颗粒塑料沙的群体沉速及起动流速，认为塑料沙有可能保证各粒径级的沉降和起动与天然悬移质泥沙相似．The experimental study results of settling velocity and incipient velocity of fine plastic particles are presented is this article. It is found that fine plastic particles is a suitable material to be used in model test to simulate the prototype sediment in the Three Gorges Project in Yangtze River.

关 键 词：塑料沙 群体沉速 起动流速 冲淤 模型试验
