摘要
抚州市文昌桥地处抚河主河道最窄处，抚河主河道平均宽度为400～600m，而该处行洪净宽不足160m，汛期阻水非常严重。根据抚州市桥东防洪墙现状及该段河道上下游地形情况，通过堤线布置方案比较、治理前后水面线分析，提出了拆除桥东防洪墙并使其后退方案，较大缓解了文昌桥度汛压力，对类似工程设计具有一定的参考价值。
The Wenchang bridge is located in the narrow channel of Fuhe River, and the average width of the main channel is about 40@600 m. But the flood width of this place is less than 160 m. During the flood season, the bridge holds back the flood seriously. According to the present situation of Qiaodong flood wall in Fuzhou City and the upstream and downstream terrain of the river, the scheme of demolishing Qiaodong flood wall and making it back off is chosen through the comparison of the dike line layout and the analysis of water surface line before and after the treatment. The method can greatly relieve the Wenchang bridge flood prevention pressure, which has some value for the design of similar engineering project.
