This course is one of the core tasks of tunnel construction safety management. Through the study of this course, we can master the basic theory and methods of tunnel construction ventilation, including the design of tunnel construction ventilation, the implementation of tunnel construction ventilation, the precautions for tunnel construction ventilation, and have the ability to engage in general tunnel construction ventilation management. At the same time, the virtual simulation experiment system of tunnel construction ventilation is developed. The virtual simulation experiment system has a bilingual display interface in Chinese and English. Through human-computer interaction and the combination of theory and practice, the practical skills of students and the quality of talent training are effectively improved. It has made positive contributions to cultivating talents with cross-cultural communication and practical innovation ability and serving the national the Belt and Road strategy.
