摘      要：Artificial reef is a man-made object that is deployed purposefully on the seafloor to restore the offshore fishery resources and the ecological *** secure its ecological effects,it is important to study the possible instability of artificial reefs,like drifting and reversing caused by burial and scour in different seafloor *** the present study,experiments of local scour around an artificial reef are carried out in steady *** effect of the open-area ratios and the open-hole heights of the cubic reefs,and the bottom angles of the triangular reefs on the time-scale of the scour process and the equilibrium scour depth are *** results indicate that for the cubic artificial reef,the scour depth decreases with the increasing open-area ratios,and increases with the increasing open-hole *** the present study,the optimal prototype of the cubic reef with an open-area ratio of 0.49 and open-height of 0.7 m produces the minimum scour *** the triangular reef,the scour depth increases when the bottom angle ***,based on the experimental results,empirical equations of the effects of the cut-opening and the bottom angle on the maximum equilibrium scour depth are *** formulas will provide theoretical support and practical guidance for the optimized design and construction of artificial reefs.
