摘　　要：探讨了不同类型泥沙物理模型的主要相似准则、模型沙选择、时间变态的处理、冲淤验证资料的选取、局部动床的范围、动床模型试验的重复性等问题,并以杭州湾大桥动床模型试验为例予以进一步说明。The major similarity criteria for different kinds of sediment physical models, the selection of model sand, the treatment of time distortion, the selection of verification data for erosion and siltation, the range of local movable bed and the test repeatability of movable bed models were studied. Further explanation was depicted by the physical movable bed model for Hangzhou Bay Bridge.
