China’s infrastructure construction has been evolved into the new era, which puts forward higher requirements for the traditional teaching and the practical application ability of college graduates. The matching degree of teaching cases and specialty is not satisfactory in urban underground space engineering specialty, and it is dramatically inconsistent with students’ experiences and society actual under the standard of innovation, high order and challenge, this is unsuitable for cultivating students’ ability and quality. Based on urban underground space engineering, the paper explores the specific teaching case from a practical engineering. With Rankine’s earth pressure theory, discusses the implementation of teaching case, stimulates students’ initiative, and provides a good practical foundation for the practical application ability of college graduates.
