摘要
根据泥沙数学模型的计算分析，对三峡水库修建后坝下游河床冲刷发展规律进行探讨，并论述了因河床冲刷引起的河床变化、沿程含沙量恢复以及下游各站水位下降等变化趋势。
Based on calculation and analysis of the sediment mathematical model, the evolution process of downstream river bed scour after completion of the TGP has been researched. The tendency of the river variation, sediment concentration recovery and degradation of level along the river channel, caused from the river bed erosion, has been proved.
