In order to strengthen the cultivation of students' professional interest, application and innovation ability and practical ability to solve complex engineering problems, the ideas of the construction and application of virtual simulation experimental teaching resources serving the triple-leveled professional curriculum system, namely the "core-direction-expansion" curriculum system of civil engineering are proposed. The three-level curriculum system has the characteristics of organically connecting theoretical teaching, practical teaching and engineering practice with experimental teaching. The course of "Comprehensive Experiment of Civil Engineering (including Virtual Simulation)" with the characteristics of " Virtual-Real Combination " is newly established, which contains the experimental teaching content urgently needed by civil engineering majors, and adapts to the new characteristics of college students' growth and new laws of education and teaching in the information age. Relying on the national-level experimental teaching demonstration center, the national-level virtual simulation experimental teaching project and a number of teaching research and teaching reform subjects, the virtual simulation experimental resource library serving the triple-leveled curriculum system is built with the "Golden Course" standard of virtual simulation, and the three-dimensional teaching resources are constructed combined with the virtual simulation projects，courses construction and teaching material construction.
