| Abstract: | Two-dimensional mathematical model of water flow was used to conduct feasibility study on the Qingbaijiang railway bridge.By comparing water condition changes before and after the bridge construction,the scouring impact of velocity around bridge piers and change of water surface line on piers was investigated.The feasibility of railway bridge provided technical support for the implementation of the project. |
