Abstract

Abstract: Stream fields calculating software SMS is applied to verify two dimensional flow field numerical model，utilizing actual measured Tuojiang River velocity and water level data． Stream fields of river in different conditions is calculated，and the impaction of piers to Tuojiang River’s stream fields after constructing bridge is also analyzed，which lays a foundation for river bed scour analysis and formulating reasonable protective measures．

Key words: two dimensional, pier, stream field

摘要： 应用流场计算分析软件SMS，利用实测沱江流速和水位数据对建立的二维流场数值模型进行验证，并计算不同工况下河流流场，分析建桥后桥墩对沱江流场的影响，为河床冲刷分析和合理防护措施的制定奠定了基础。
