摘要:
分析了沙集闸站前池泥沙淤积成因,并试图改造在下游新建清污机桥,应用桥墩改善前池流态、减少泥沙淤积,采用三维建模软件UG NX建立河道流场三维模型,基于ICEM CFD进行计算域网格划分,并使用ANSYS CFX进行数值计算。计算结果表明:现状抽水工况下,导流墙内侧存在大范围低速区,因而产生大范围泥沙淤积。将泵站下游两侧导流墙延长至60 m,在导流墙头部新建清污机桥,应用桥墩导流,导流墙内侧低速淤积区范围大大减小,泵站进水流态大为改善。
Abstract:
This paper analyzed the causes of sediment deposition in the front pool of Shaji Sluice Station, and tried to rebuild the new cleaning machine bridge in the downstream. The bridge piers were used to improve the flow pattern of the front pool and reduce sediment deposition. The three-dimensional modeling software UG NX was used to establish a three-dimensional model of the river flow field, and ICEM CFD was used for computational domain mesh division. ANSYS CFX was used for numerical calculation. The calculation results indicate that under the current pumping conditions, there is a large-scale low-speed zone on the inner side of the diversion wall, resulting in large-scale sediment deposition. Extend the diversion walls on both sides downstream of the pump station to 60 meters, build a new cleaning machine bridge at the head of the diversion wall, and use bridge piers for diversion. The low-speed sedimentation area on the inner side of the diversion wall is greatly reduced, and the inflow flow pattern of the pump station is greatly improved.
