Under the background of first-class curriculum construction, the professional curriculum of engineering specialty should also be carried out the reconstruction of teaching content and resources in time, so as to lay an important foundation for the teaching design and implementation of the curriculum. Taking the tunnel engineering course as an example, this paper analyzed the difficulties in the current course teaching, and introduced the teaching content organization ideas of engineering courses, including programmatic syllabus compilation, structured knowledge system design, modular teaching content organization, practical teaching resource allocation, systematic ideological and political elements, etc. Through a complete teaching content organization, rich teaching resources and a comprehensive ideological and political element system, a relatively complete teaching content and teaching resources have been formed to help achieve the goal of first-class curriculum construction.
