摘　　要：以模型相似原理为基础，结合黄河小浪底至花园口河段河道整治模型试验研究，对河型变化段河工动床模型设计方法进行了初步探索，提出了“分段设计、过渡处理”的设计方法，辩证地解决了同一模型具有不同河型河段的河工动床模型设计问题。Based on principles of physical model similarities, and practice of model test for river training in the reach from Xiaolangdi to Huayuankou of the Yellow River, the design for movable bed model in a reach with different river patterns is studied. The method suggests using different similarity criteria for different river pattern sub reaches and obtains satisfied results in calibration.
