摘　　要：平原河流河漫滩护坡工程顶部与滩面衔接处常受到水流淘刷而导致护坡破坏。以长江中游丙寅洲守护工程为依托,参考边滩的护滩带结构,对丙寅洲滩面上流速较大的上游段护坡顶部与滩面的衔接区采取护滩带间距守护措施。通过概化定床与动床水槽试验,研究不同护滩带间距、高度对滩面水流结构与滩面稳定性的影响,优化守护工程措施。研究结果表明,在滩面流速相对较小的区域,采取护滩带间距守护措施的工程效果较好。The plain river flat slope protection is often damaged at the connecting part of the top and shoal face due to current scouring. Based on Bingyinzhou shoal protection engineering in the middle reach of the Yangtze River and referring to the protection structure, we take spacing-guaranteeing measures at the connecting part of the top and shoal face, where the current speed is relatively large. By generalized fixed-bed and flume experiment, we study the influence of different spacings and heights of the shoal protection on the flow structure and stability of the shoal face and optimize the protection engineering measures. The research results show that in the area of relatively small beach-face velocity, the spacing-guarantee measure is better.
