This situation demands an evolution in the pedagogical approaches within civil engineering disciplines. The project method emerges as a potent strategy for educators to enhance their instructional techniques. It facilitates the integration of theoretical insights with practical applications through case studies, thereby equipping students with a profound understanding of knowledge, techniques, and methodologies. This method not only aids in the internalization of information but also shapes students into versatile, applied-knowledge professionals. With this in mind, the forthcoming discourse centers on the pedagogical reform of Deep Foundation Pit Excavation and Support. It delves into the distinctive attributes of the project method within civil engineering education, scrutinizes case studies pertinent to the course content, and outlines strategic approaches to curriculum reform, all aimed at offering a reference for further academic and practical advancements.展开更多
