Abstract: Tunnel engineering is a practical discipline integrating engineering survey, design, construction and management, its theoretical knowledge is closely combined with the project site. The basic theory of this discipline is abstract and difficult to understand, and the knowledge system is complex and trivial, resulting in students' inability to remember and remember professional knowledge, resulting in students' low enthusiasm for professional knowledge learning. Practice scene video teaching is a new teaching mode with both audio and video, which can improve students' innovation level and enhance students' practical ability. By analyzing the difficult problems faced by tunnel engineering teaching, this paper explores the innovative application of practice scene video teaching in the course of tunnel engineering, in order to seek a teaching method that organically combines theoretical research with construction practice, improve students' innovation ability and stimulate students' initiative to seek knowledge.

Key words: Practice scene, Video teaching, Tunnel engineering teaching innovation, Engineering practice, Field application
