Abstract: New infrastructure is the driving force of the economic growth in China, which could seriously affect the industrial development and education system and of the existing old infrastructure, like the civil engineering, in return. From this viewpoint, a four-stage reform plan on course of foundation pit engineering, which is one of the courses in the civil engineering, was proposed and practiced. The reform was based on the knowledge fusion of the new infrastructure and old infrastructure. It aims to teach the students from civil engineering with the market-demanded knowledge from new infrastructure. Moreover, it attempts to explore a universe routine for course reform in civil engineering when incorporating the knowledge of new infrastructure. Guided by this reform plan, students could learn some basic knowledge of new infrastructure and its potential application in foundation pit engineering in 12 lectures, and then learn to adopt the technique of new infrastructure to turn the application into truth 4 labs. Most involved students agreed that the reformed course is useful and practical. However, the lessons seem to be difficult and fast in pace, since they did not have enough background knowledge of the new infrastructure before taking the course. Yet, they concurred that the arrangement of the lessons was appropriate, demonstrating that the four-stage reform plan is effective and of practice value.
