摘　　要：河工动床模型至今仍主要进行定性相似模拟研究,靠加大尺度的模型试验并不能明显改进试验成果,决非最佳选择。尽管微尺度模型远未完美,作为河工动床模型的创新值得关注。The loose-bed hydraulic models are still at the qualitatively study level. Without the breakthrough in basic theories concerned only enlarging model dimensions could not improve the accuracy and reliability of the experiment results evidently, which means that it's not the best of alternatives available. Although the micromodel is far away from the perfection, it is an innovation that should be paid more attentions and efforts.
