摘　　要：通过应用非线性三维紊流数值模型,并采用有限体积法对模型控制方程进行离散,对非淹没丁坝绕流进行数值模拟仿真分析,给出了三维流场、压力分布场、剪应力分布场等信息,计算结果均基本符合非淹没丁坝绕流的实际情况,结果表明该非线性模型是可取的,数值模拟结果具有一定的可信度。With the non-linear turbulence flow model,we carried out a 3D-circumferential flow numerical simulation to an unsubmerged spur dike by means of the scattering about the controlling equation with FVM,and analyzed the complicated 3D-torrent near the spur dike,gave the 3D-torrent near the spur dike,3D-flow distribution,pressure and shear stress distribution on the surface of spur dike and in the bed near the spur dike.The result of the 3D-circumferential flow numerical simulation accorded basically with the actual situation.So it is proved that the non-linear turbulence flow model is applicable and the numerical simulation result is reliable.
