Objective Under the promotion of the construction of new engineering course， it is imperative to reform the practical teaching system of civil engineering majors based on virtual simulation technology.Method Based on the analysis of the problems existing in the traditional practical teaching system of civil engineering majors， combined with the actual construction of provincial virtual simulation centers， this paper explored the goals， contents， and paths of the construction of virtual simulation practical teaching system.Result After several years of construction, a practical teaching system of modular virtual simulation has been formed based on the principles of "combining reality and virtuality, innovation leading, and practice directing", driven by three dimensions: integration of science and education, integration of industry and education, and collaborative education.Conclusion The above system has improved the quality of practical teaching， stimulated students'' interest in learning and innovation ability， and can provide ideas for the reform of practical teaching in engineering majors.
