| 摘 要： | 采用基于计算流体动力学模型的方法对人工鱼礁流场效应进行数值模拟，选取单体人工鱼礁模拟近岸海域的鱼礁流场，对其附近流场进行三维数值模拟，在此基础上应用双因素方差分析法分析了人工鱼礁开口比和迎流面形状对流场效应的影响。结果表明：人工鱼礁开口比是鱼礁流场效应的主要影响因素，开口比越小，水流受鱼礁阻隔程度越大，礁前上升流流速越大，背涡流紊流区域越明显，背涡流区域就越长；鱼礁迎流面形状对流场效应的影响次之。 |

| Abstract: | The flowing field of artificial fish-reefs was simulated numerically by computational fluid dynamics meth- od, and an individual artificial fish-reef was chosen to simulate the three dimensional flowing field in coastal sea. The effects of opening ratios and surface shape facing flowing of fish-reefs on flow field were analyzed by two-way analysis of variance. The result showed that the opening ratio of the fish-reef was the major factor influencing flow- ing field, that the less the opening ratio of artificial reefs was, the more significantly water flow was obstructed, the faster the speed of upward flowing before reef, the more noticeable the turbulence of reverse vortex flow was, the longer the reverse vortex flow area was, and that, the effect of the shape of reef was surface on flow field was found to be less significant than that of the opening ratio of artificial reefs. |
| Keywords: | artificial reef opening ratio shape of reef surface two-way analysis of variance flow field effect |
