利用现代模型相似理论及关于异重流运动相似条件的研究成果，在分析原型资料和对模型沙特性比选的基础上进行模型设计；同时利用三门峡水库实测资料完成了模型验证试验；在模型设计及验证试验的基础上，研究了水库在拟定的运用方式下泥沙运动规律、泥沙淤积机理及河床纵横剖面形态变化等。
Using the modern model similarity theory and the research results on the similar conditions of gravity flow movement, the model design is done on the basis of analyzing the prototype data and comparing the model sand characteristics. At the same time, the model verification test is completed by using the measured data of Sanmenxia Reservoir. And verification tests, the sediment movement law, sedimentation mechanism and the vertical and horizontal cross-section shape changes of reservoirs under the proposed application mode are studied.
