摘　　要：针对水下中部悬置构筑物,本文基于ANSYS中的Fluent和Aqwa模块,比较了单索单点系泊、三索单点系泊、三索三点系泊及球形、圆柱-半球形、碟形三种外形对其水中稳定性的影响。由数值模拟结果显示,在200 m水深,水流速度为2 m/s作用下,碟形构筑物采用三索单点系泊方式的稳定性更为优。Aiming at suspended mid-ocean structure, Fluent and Aqwa was used to compare the effects of single mooring, single-point mooring with three anchor chains, three-point mooring with three anchor chains and three shapes of ball, cylinder-hemispherical and saucer on the stability of structures. The results of numerical simulation show that, under the action of 2 m/s water velocity in 200 m water depth, the stability of the structureswhen fixed by single-point mooring with three anchor chains in the shape of saucer is better.
