中文摘要:

为分析副桥的修建对原河道水流特性的影响,以副桥工程为例,采用MIKE21水动力模型模拟了100年一遇设计洪水条件下河道内水位和流场的变化。结果表明:副桥修建后只是在桥墩附近产生一定的壅水和流场变化,对河道水流影响具有局部性。

英文摘要:

In order to analyze the influence of auxiltary bridge on river flow characters,this paper used hydrodynamic model of MIKE21 to simulate the change of water level and flow field under flood once every 100 years.The results showed that after construction of the auxiliary bridge pier produced contain effect on backwater and variation of flow field.However,the influence created by the auxiliary bridge was still limited.
