In the context of new engineering construction, case teaching method is an effective way to train high-quality talents for Master of Civil Engineering and Hydraulic Engineering. Therefore, it is necessary to establish a perfect teaching case base to improve the practical ability of graduate students. Considering the ideological education and school-enterprise cooperation, the paper studies the problem of case base construction for civil and hydraulic masters in civil engineering. This paper mainly includes the main frame of case base construction, the subject of the case base, the source of case resources, the sharing mechanism of the case base. The main purpose of this paper is to provide theoretical thinking and practical guidance for the construction of professional course case base.
