摘　　要：论述了三峡水库蓄水运用前后长江中游芦家河水道演变特征,分析了航道条件的变化,指出该水道当前的主要碍航问题是"坡陡流急",并对其成因与演变趋势进行了分析研究,根据分析研究的成果提出了该水道的治理原则和治理对策,并给出了物理模型上该水道在方案实施前后的效果对比。We investigate the morphological evolution of Lujiahe waterway before and after the impoundment of the Three Gorges reservoir,and analyze the change of the navigation conditions.It is pointed out that the ＂steep slope and torrent flow＂ is one of the navigation obstructions,the reasons and evolution trend of which are studied in this paper.According to the research results,we put forward the training principle and measures for the waterway,and present the contrast of the waterway before and after the implementation of the regulation scheme.
