摘　　要：牯牛沙水道为长江中游重点碍航水道之一,整治其水道对畅通长江中游航道具有重要意义。结合研究河段近期河床演变特点,针对长江中游牯牛沙水道航道整治二期工程初步设计中原护岸加固工程的平面布置提出优化方案,并进行设计分析。结果表明,护岸加固工程平面布置优化方案将护岸加固长度减少200 m,将加固抛石量减少至7. 3万m3,平顺式护岸岸坡满足整体设计稳定要求,可为顺利实施二期航道整治工程和保障通航安全等提供重要技术支撑,并为类似工程设计提供参考。Guniusha waterway is one of the key navigable waterways in the middle reaches of the Yangtze River.It is of great significance to control the channel well for the smooth passage of the middle reaches of the Yangtze River.Combining with the recent evolutional characteristics of Guniusha waterway in the middle reaches of the Yangtze River,and aiming at the revetment reinforcement layout scheme in the initial design report of Guniusha waterway second phase channel regulation project,we present the optimization plan,and carry out the special design analysis and the checking calculation of the structural stability.The results indicate that the reinforcement length of the bank protection engineering can be reduced by 200 m,and the riprap amount in reinforcement engineering can also be reduced to 73,000 m^3.The smooth bank slope meets the stability requirement of the whole design.It can provide a technical support for the second stage waterway regulation project and guarantee of safe navigation,and may serve as reference for the design of similar projects as well.
