摘　　要：实测了导流型人工鱼礁体在纵向布设间距1.0L(L为礁体长度)和2.0L下的流场及受力特性,计算了导流型人工鱼礁体在横向布设间距(0.5L、1.0L、1.5L、2.0L)及纵向间距(0.5L、1.0L、2.0L、3.0L、4.0L、5.0L)下的水动力特性,研究结果表明:导流型人工鱼礁体流速及阻力系数的计算值与实测值吻合较好;横向布设下上升流高度、阻力系数均与布设间距成反比,0.5L时,上升流高度较大,1.0L时,上升流体积较大;纵向布设下上升流高度较平稳,上升流水平跨度、上升流体积与布设间距成正比,大于4.0L时,趋于平缓,4.0L时,流场效应较好.通过上述不同纵横间距比的组合优化研究,可在工程中为人工鱼礁体选型、设计和布设提供参考.The velocity and force of artificial reef at the distance of 1.0L and 2.0L in the flow direction are measured.Then hydrodynamic parameters of artificial reef at the distance of 0.5L,1.0L,1.5L and 2.0L in the vertical direction and the distance of 0.5L,1.0L,2.0L,3.0L,4.0L and 5.0L in the flow direction are calculated.Results show the consistency of the velocity and the drag coefficient.When the artificial reef is placed in the vertical direction,the height of upwelling and the drag coefficient decrease with the distance increases.When the distance reaches 0.5L,the height of upwelling becomes the largest,whereas when the distance reaches 1.0L,the volume of upwelling is the largest.When the artificial reef is placed in the flow direction,the height of upwelling changes slightly.Also,the horizontal span of upwelling and the volume of upwelling increase with the increase of distance.When the distance reaches 4.0L,the increase speed is slow,and the flow field effect is best when the distance equals 4.0L.Finally,this study provides references for the design and layout of artificial reef.
