摘要
在国家大力建设跨越江、海桥梁工程的背景下,桥梁水动力学作为影响结构设计的关键内容,其课程教学显得尤为关键。然而,因为水动力学与传统结构分析差异较大,理论推导过程复杂,导致其教学过程较为抽象、理解较为困难。结合当前桥梁水动力学课程教学现状,提出将CFD仿真技术作为辅助教学方法引入到课程教学中,以帮助学生深入理解桥梁水动力学的概念和公式。利用CFD仿真技术的图形显示功能,描述了水流、波浪等对桥梁下部结构的荷载作用以及基础冲刷演变过程,生动地向学生展示文字难以描述的水动力作用现象,进而使得学生对该部分理论知识的理解更为深刻。
With the construction of the sea and river crossing bridges,Bridge Hydrodynamics is becoming more and more particularly important in the bridge course teaching as a critical component affecting structural design.As a result of the significant difference between hydrodynamics and traditional structural analysis and the complex theoretical derivation process,the teaching process becomes more abstract and challenging to understand.Combining the current teaching situation of bridge hydrodynamics,this paper introduced CFD simulation technology as an auxiliary teaching method in the course teaching to help students deeply understand the concepts and formulas of Bridge Hydrodynamics.The graphic display function of CFD simulation technology could vividly show the hydrodynamic phenomena difficult to describe in words,such as the current and wave force of the bridge substructure,the evolution process of the scour of foundation,and so on,and then help students have a deeper understanding of theoretical knowledge.
