As an important supporting discipline for infrastructure construction and urban development， civil engineering is crucial to accelerating the process of national modernization and enhancing international competitiveness. However， the traditional civil engineering education mode has been difficult to meet the current social demand for high-level and interdisciplinary talents. Based on the concept of integration of science and education， this paper constructs a four-in-one training mode of research-teaching-practice-entrepreneurship for civil engineering postgraduates. Through the science-education collaboration platform， hierarchical training program and policy guarantee mechanism， problems such as disconnection of innovation education and insufficient practice platform in the traditional mode are effectively solved. Empirical data from 2019 to 2023 shows that the average annual growth rate of postgraduates’ SCI/EI papers is 25%， 76 patent applications are filed， and the transformation rate of technological achievements is 35%； the employment rate of graduates in leading enterprises reaches 88%. The research confirms that this mode provides a reproducible paradigm for talent training by connecting national strategies. In the future， it is necessary to deepen interdisciplinary integration and technological innovation to meet the intelligent and sustainable development needs of the industry.
