Abstract Research purposes：At present,foreign and domestic study on information management system for tunnel engineering monitoring mainly remains in simple chart analysis of monitoring data under 2D view.A few system achieved information query under 3D condition,but the tunnel model is relatively rough and the information is single.In this paper,the technology of 3D real-time interactive visualization was apply to develop tunnel monitoring information platform where the tunnel model had almost real and rich information.
Research conclusions：(1)Using R-Trees to create a spatial index can achieve an efficient management of huge amounts of data.(2)The tunnel engineering monitoring 3D real—time interactive visual information platform we studied combines building 3D scene of tunnel quickly interactive roaming and information query into one.You Can browse the scene smoothly,and the information is abundant and complete.(3)The practice proves that using the information platform can improve the visualization and interactivity of the tunnel monitoring for users,which greatly improves the work efficiency.(4)This research result can be applied to 3D visualization management of tunnel,railway,highway, urban rail transit and other engineering fields.
