In response to the new demands for talent in the civil and hydraulic engineering industry posed by intelligent construction and green low-carbon development, traditional postgraduate practice bases urgently need improvements in aspects such as functional synergy and evaluation mechanisms. This study takes intelligent technology and the green concept as dual core drivers to construct a "teaching-research-service" trinity and deeply collaborative industry-university practice base construction model for professional master's students. By establishing a balance of interest and risk mechanisms, designing a "three-stage progressive" training path, and creating a digitally integrated virtual-physical platform, alongside the introduction of a PDCA cycle for dynamic evaluation, this model systematically enhances the engineering practice and innovation capabilities of postgraduates. Using the collaboration between the Civil and Hydraulic Engineering major at Jiaxing University and the first batch of co-established practice bases as an example, this approach highlights the organic integration of supervisors' research directions with the specific needs of enterprises, effectively promoting technological breakthroughs and the transformation of results. It provides a theoretical reference and practical paradigm for the construction of practice bases in similar disciplines.
