Shield tunneling has become an attractive method in the development of underground space. In recent years, engineers have been faced with pressure to reduce tunnel maintenance fees. Thus, this paper presents a web-based digital platform as a management tool to manage, query and visualize shield tunnel operation data. First, a data standard involving monitoring, inspection and maintenance is proposed based on existing engineering data standards and shield tunnel projects. The data standard is needed to collect data and design the database. Then a web-based digital platform is developed based on WebGIS software and Web Service Technology. Users can obtain all the engineering information through this platform. A novel feature of this system is an ability to share, update and analyze data through the internet in a visual way. The functions implemented in the platform include monitoring point positioning, historical monitoring data queries, alarm monitoring, maintenance data queries and maintenance data analysis. A case study of the Shanghai Metro Line No. 13 is presented. Compared with traditional tunnel operation management system, the digital platform provides a more effective way to manage the massive data set.
