摘要：Flood control impact assessment of construction projects within the scope of river course management shall be conducted in accordance with relevant laws and regulations. The calculation of backwater is an important content of flood control evaluation of Bridges across rivers. Two-dimensional mathematical model is a main method for flood control evaluation of backwater calculation. This paper introduces the basic principle of the two-dimensional mathematical model and applies the two-dimensional mathematical model in the actual application of flood control evaluation of the great Darui Railway Bridge of Ruili River, analyzes the changes of water level, flow rate and flow direction before and after the construction of the bridge, and uses the standard formula method to check. The results show that the two-dimension mathematical model has a high accuracy in the calculation of backwater of flood control evaluation of Bridges over mountainous rivers, which can provide scientific basis for flood control evaluation of projects.
