针对方体、梯形台和半球等形式的人工鱼礁,采用数值模拟方法,分析这3种人工鱼礁自身的阻流特性以及人工鱼礁的存在对桩基础周围水动力特性的影响。结果表明：对比3种人工鱼礁的回流区范围,梯形台鱼礁最大,半球鱼礁次之,方体最小;方体和梯形台人工鱼礁海床面最大剪切应力均随鱼礁与单桩距离的减小呈增大趋势,半球人工鱼礁则随鱼礁与单桩距离的减小呈减小趋势。
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.
