摘要: 建立了二维水流数学模型,对青白江铁路大桥进行可行性分析。比较了工程建设前后桥区水域条件变化情况; 分析了桥墩周围流速、水面线变化对桥墩的冲刷作用;论证了铁路桥工程可行性,为该工程的实施提供技术支持。

关键词: 二维水流数学模型, 有限元法, 防洪

Abstract: Two-dimensiona lmathem atical 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 im pact 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 implem entation of the project

Key words: planar 2-D water mathematical model, finite element method, flood control
