防冲墙前缘冲刷坑系列模型实验研究

On Series Model Test of Scour Pit in Front of Anti-scour Wall

以燕子窝心滩防冲墙工程为依托,结合系列模型实验成果,研究了防冲墙工程前后心滩头部水流性态和冲刷特性,提出了优化防冲墙和护滩设计方案。研究成果为工程安全可靠提供了有力的技术支撑,研究方法可为航道整治工程其它新结构型式的引用和研究提供参考借鉴。

Relying on the anti-scour wall of centre bar in Jiayu-Yanziwo channel, and according to the results of series model test, we carry out a research on the flow property and scouring characteristics of centre bar head before and after the anti-scour wall engineering, and propose optimized anti-scour wall design and conservation programs. The research results provide a strong technical support on safety and reliability of the project, and the research methods provide a reference for application and research of other new types of structures of channel regulation engineering.
