摘　　要：动床模型试验布置模型沙是模拟泥沙运动试验中的关键。模型布置模型沙之前,依据相似理论,按照一定的几何比尺选择适当的模型沙,这对于确保试验的可靠性、稳定性和提高试验精度尤为重要。本文以一港口物理模型试验为实例说明模型沙选择和布置模型沙对模拟泥沙运动的重要性。To set the model sands for marine mobile bed physical model experiment is the key in the experiment to simulate the sediment movement. In order to ensure the reliability, stability and accuracy of model experiment, it is very important to select suitable model sands based on the similarity theory before setting the model sands. In this paper, the selection of model sands and the importance of setting model sands for simulating the sediment movement are expounded by taking a harbor physical model experiment as an example.
