Abstract: To address the disconnect between theoretical knowledge and engineering practice in traditional bridge engineering education, the integration and application of simulation modeling technology in bridge engineering courses was explored in this study. Using the professional software Midas Civil as a technical platform, a triadic teaching model of“classroom 3D visualization - virtual simulation practice - case-based teaching”is constructed. Through techniques such as parametric modeling, load condition simulation, and structural response visualization, the mechanical principles of bridges are presented in an intuitive manner, effectively mitigating the abstract nature of structural behavior comprehension in traditional teaching. The results indicate that simulation modeling technology can significantly enhance students'understanding of bridge structural mechanics, stimulate interest in learning, and improve practical engineering skills, providing new ideas for the reform of bridge engineering course instruction.
