基于根石探测技术黄河宁夏段丁坝冲深研究

Studies on scouring depth of spur dike in Ningxia Section of Yellow River by root stone detection technology

梳理分析2013年完成的黄河宁夏河段水下根石探测成果,并对比传统的经验公式计算结果,提出了宁夏河段合理的丁坝设计冲刷深度建议值,即仁存渡以上河段取12.9 m,仁存渡以下河段取16.0 m,有利于河道整治工程运行安全。

A systematical study has been conducted on underwater root stone detection in Ningxia Section of the Yellow River completed in 2013, and its result is compared with that of the traditional empirical formula. A proper scouring depth designed for spur dike is suggested for the river course in Ningxia, i.e. 12.9 m above and 16.0 m below the river section of Rencundu, which shall be suitable for the operation and maintenance of river training project.
