Abstract: Training teaching based on virtual simulation technology is a hot development direction in the field of vocational education. In order to give full play to the advantages of virtual simulation technology in the training teaching of higher vocational colleges, starting from the practical application of road and bridge professional construction technology training teaching, and with the cooperation of construction enterprises, a practical and practical training teaching mode was constructed and developed. A virtual simulation training and teaching system for road and bridge engineering construction was presented. Through the organic integration of virtual simulation technology and practical training teaching, the practical teaching of high-risk, high energy-consuming and large-scale comprehensive, process irreversible projects in the field of road and bridge engineering has been realized, which has enriched the content of student training and improved the effect of student training. At the same time, it has promoted the reform and innovation of teaching models in vocational colleges.
