为了验证以往黄河宁夏河段工程设计中丁坝设计冲刷深度取值的正确性,对2013年完成的水下根石探测成果进行分析,并对比传统的经验公式计算结果,证明丁坝设计冲刷深度仁存渡以上河段取9 m、仁存渡以下河段取14 m符合宁夏河段实际情况,可以作为设计值采用。
In order to verify the reach of the Yellow River in Ningxia engineering design,the correctness of the spur dike design scour depth values,the underwater root stone detection results of 2013 was analyzed,and compared with the traditional empirical formula calculation re-sults,proved that spur dike design scour depth upper reaches of Rencundu took 9 m and downstream of Rencundu took 14 m could be used as a design value which accorded with the actual situation of Ningxia section.
