Abstract: Railway professional design institute has accumulated a wealth of railway design cases in long-term railway construction project design. In order to make up for the deficiency of the existing design case information management platform and solve the situation that a large number of resources do not play their due value in the new line design and staff skills improvement, this paper designed and implemented the railway survey and design case informatization management system based on B/S architecture, and introduced the overall architecture and specific function implementation of the system. The system can collect and manage the railway survey and design data comprehensively, and realize the quick query, analysis and utilization of the existing design data. It is convenient for professional designers to learn, refer to and use the existing case materials and the knowledge and experience of technical experts quickly and effectively.
