Abstract: Based on an introduction to the construction and application of the early warning control platform for the tunnel and subway engineering, an overall analysis of the related data during tunnel and subway construction was conducted in order to give a better reference for the site construction, to guarantee safe and rapid qualified construction, and to improve management efficiency. Based on red line control, deformation thresholds of surrounding rock,allowances of construction material and advanced geological prediction, a dual early warning system with automatic trigging and manual prejudging was adopted to control the quality of tunnels and subways and to guarantee safe construction; through the platform a centralized management is realized, all the construction information and effective data are transmitted instantaneously by internet, decreasing management cost and increasing work efficiency.
