在贴体正交坐标系下建立了乌江羊角大桥河段的平面二维水流数学模型,研究了羊角大桥修建后工程段乌江河道水流条件的变化。结果表明,拟建工程对该乌江河段的河道防洪、河床演变及涉河工程安全的影响不大。 A two-dimensional mathematical model of two-dimensional water flow was established in the orthogonal body coordinate system of Wujiang River Bridge, and the variation of water flow conditions in the Wujiang River channel after the construction of the Sheyang Kok Bridge was studied. The results show that the proposed project has little effect on the river flood control, river bed evolution and river-crossing safety in the Wujiang reach.
