摘　　要：界牌河段位于长江中游,河床演变复杂,洲滩变化剧烈。在总结该河段演变规律的基础上,开展了航道整治工程。结合已建工程,综合分析河道近期变化特点,进行整治效果分析。分析结果表明,整治工程抑制了航道条件不利变化趋势,使过渡段低滩滩形基本稳定、位置得到控制,为本河段后续治理工程奠定了良好的基础,也取得了长顺直河段治理的经验。Jiepai reach lies in the middle of the Yangtze River.Its riverbed evolution is complicated and the beach has changed dramatically.Based on the summarization of the river’s evolution law,we carry out the waterway regulation works.Combining with the existing projects,we analyze the regulation effect.The analyzing result reveals that the regulation projects have inhibited the adverse changes of the channel conditions,the low beach at the transition section is basically stable,and the transition position is controlled.It lays a good foundation for the follow-up treatment of the reaches,and obtains experience for the long and straight river regulation.
