Abstract: Graduation design is an important practical teaching link of undergraduate training. This article addresses the issue of poor quality undergraduate graduation designs for the emerging urban underground space engineering major. Based on the practical experience of graduation design guidance, it analyzes the current traditional graduation design mode and existing problems, graduation design pattern is discussed based on the concept of CDIO - OBE concept through actual engineering project and school-enterprise cooperation in urban underground space engineering. A circular mechanism of continuous improvement of graduation design practice teaching link is formed and the transformation and upgrading of traditional graduation design practice teaching link is promoted to improve the education quality of urban underground space engineering.

Key words: Graduation design, CDIO, OBE, Urban underground space engineering, Practical ability, Teaching reform, School-enterprise cooperation
