摘要
采用圣维南方程组建立三峡库区日调节通航水流条件一维数学模型,利用三峡枢纽淤积平衡地形日调节物理模型试验成果对数学模型进行验证。研究表明,24h日调节过程中,流量变化的时候,上游引航道通航水流条件最不利。随着泥沙淤积年份增加,汛期日调节通航水流条件逐渐恶化。电站机组错时开启或关闭可以减小口门处的流速。
A 1-D numerical model was bulit according to the Saint-venant Equations,and verified by the data of Three-gorges Project physical model test.The study shows that when the flow is changed,the upstream navigation conditions will be the worst.By changing the flow in two times,the average velocity at the channel entrance will be decreased.
