Abstract

In this work, three different artificial reefs, namely cube, trapezoidal and hemispherical artificial reefs, are studied by numerical simulation method to analyze the flow obstruction characteristics of these three artificial reefs and the influence of arrangement on the hydrodynamic characteristics around the pile foundation. The results show that the trapezoidal artificial reef is larger than the hemisphere and larger than the cube in the range of the backflow area of the three artificial reefs. With the decrease of the distance between the cube and the trapezoidal artificial reef and the cylinder, the maximum shear stress of the seabed shows an increasing trend, while the influence of the hemispheric artificial reef on the maximum shear stress of the seabed shows a decreasing trend with the decrease of the distance between the real and the monopile.
