摘　　要： 本文提供的数学模型是以大量实测资料为基础，根据水库泥沙冲淤的特点，在考虑壅水淤积的同时，还考虑了库水位变动所引起的溯源冲刷对河床形态的影响而建立的计算水库泥沙冲淤过程的数学模型，还用本模型再现了白龙江碧口水库的冲淤过程，计算结果与实测值符合良好。本模型可供水库管理，尤其是工程设计部门使用。This paper studies mathematical model for reservior sedimentation. With the determinationof deposit distribution and retrogressive scouring,the mathematical medel for predicting of sedimenta-tion processes in reservior was eetablished.The advantages of this model presented in the paper are la-rgely saving in com puter time and storage capacity. The sedimentation procese of Bikou Reservior onBailongjiang river was simulated by this model and computed results were in good agreement with thefield observations.
