【摘要】 三门峡水库自１９６０年９月中旬蓄水运用以来，先后经历了两次改建和三种不同运用方式，相应地水库的泥沙淤积也经历了几个不同阶段．本文试图利用非均匀不平衡输沙的理论，对三门峡水库泥沙淤积进行分析研究，找出各个不同时期的冲淤特点和规律，由此，对三门峡水库未来的泥沙冲淤趋势以及如何控制提出预测和建议．更多还原

【Abstract】 Two reconstructions and three kinds of different operating ways have been taken since theSanmenxia Reservoir was operated in September, 1960.Correspondingly,the reservoir’s siltationwas quite different.In this paper, some analyses of Sanmenxia Reservoir’s siltation are made byuse of the theory of non-equilibrium transportation of nonuniform suspended load, and somerules of scour an.d siltation are found.Based on these rules,some predictions and proposals tocontrol siltation and to operate the reservoir are presented.更多还原
