摘　　要：跨河桥梁的修建对河道水流特性将产生直接影响,水流条件相较于无桥墩干扰时更为复杂,因此,有必要对跨河桥梁建设项目开展防洪影响评价。为评价池州长江公铁大桥建设对河道行洪带来的影响,按相应比尺建立了物理模型,综合分析不同典型水文条件下,拟建工程对水位、流速、流场等河道行洪和防洪的影响,可为优化工程设计方案和行政部门审批提供依据。The construction of cross-river bridges will have a direct impact on the flow characteristics of the river,and the flow conditions are more complex than those without interference from bridge piers.Therefore,it is necessary to carry out flood control impact assessment for cross-river bridge construction projects.In order to evaluate the impact of the construction of the Chizhou Changjiang highway and railway bridge on river flood discharge,a physical model was established according to the corresponding scale to comprehensively analyze the impact of the proposed project on river flood discharge and flood control under different typical hydrological conditions.It can provide a basis for optimizing engineering design schemes and approval by administrative departments.
