| 摘 要： | 为维持长江口岸直水道下段目前较为有利的滩槽格局,将在鳗鱼沙心滩头部建造护滩守护工程,需要研究守护工程周边的最大冲刷深度,以确定边缘压石宽度与重点防护部位。采用1∶100与1∶200的系列水槽试验研究护滩工程周围的局部冲刷深度,试验结果表明:局部可能最大冲深6.0 m左右,结果可应用于工程设计。

| Abstract: | In order to maintain a more favorable pattern of beach slot at present in Kou’an straight reach of the Yangtze River,Manyusha shoal head protection engineering will be implemented,thus the maximum scour depth surrounding the project need to be studied to determine the width of pressure stone in edge and the key protection parts.The flume series experiments with the scale of 1∶100 and 1∶200 are used to study the local scour depth around beach protection project.The result shows that the depth of maximum local scour will be 6.0 m,which can be applied to the engineering design. |
