通过对水库泥沙研究对象和所要解决问题的深入分析 ,依据泥沙运动基本规律和大量的实测资料 ,分析了水库排沙、分组泥沙运动、泥沙沉降等计算关系 ,建立了水库泥沙冲淤计算数学模型。利用三门峡水库 1960～ 1990年实测资料对模型进行了验证 ,对小浪底水库的各种运用方案进行了冲淤计算 ,计算精度满足要求。
Based on the analysis of the object of sediment research and the problems to be solved, based on the basic law of sediment movement and a large amount of measured data, this paper analyzes the relationship between sediment discharge, sediment movement and sedimentation in reservoirs, and establishes the reservoir sediment Scouring and silting calculation mathematical model. The model was validated from the measured data of Sanmenxia Reservoir from 1960 to 1990, and the various plans of application of the Xiaolangdi Reservoir were scoured and calculated, and the calculation precision satisfied the requirements.
