摘　　要：现行黄河口北侧丁坝(进海路)是海堤重要的护堤工程,而丁坝坝头局部冲刷深度是该工程设计中的1个关键参数。本文以孤东海堤2#排涝站位置丁坝(进海路)为例,在多年实测水深地形资料的基础上,分析影响丁坝坝头局部冲刷的各种因素,建立了适用于现行黄河口北侧区域的波、流共同作用下丁坝局部冲刷的计算方法。The spur dike is one of the most important coastal constructions to protect the embankment in the northern area of the Yellow river estuary,the local scour depth is a key parameter in the design of spur dikes.In this paper,the spur dike(entrance to the sea) at the No.2 drain station in the Gudong coastal area is utilized as an example to calculate the local scour depth and based on the results of water-depth measurement,a formula is given to estimate the local scouring depth under the co-action of waves and currents.
