Based on the national construction needs and the prospect of industry development, this paper analyzes and researches the current situation and the main problems of the postgraduate training mode of traditional engineering disciplines under the construction of new engineering disciplines. Taking the development of urban underground space engineering discipline of Central South University as an example, aiming at each graduate student"s " accurate identification ", achieving a reasonable " collaborative supervision " training model in accordance with their aptitude, and the training measures for urban underground space engineering graduate students in the new situation to ensure. It also provides a practical basis for the development and reform of traditional engineering disciplines in the context of new engineering construction, with urban underground space engineering as the benchmark.
