Preliminary Study of the Geological Disaster Modeling in the Three-Dimensional Tunnel Project

摘要

There are various potential natural geological disasters in the process of tunnel construction, such as methane gas, tunnel collapse, tunnel gushing, etc. Due to the limited data collection and the invisibility of some natural phenomenon, how to simulate these geological disasters more visually and increase its early warning management more effectively has been a tough problem in three-dimensional simulation. This paper briefly describes the GIS-based three-dimensional rendering technology and the feature attribute management method to achieve the geological disasters modeling in the tunnel and its simulated prediction, which can provide auxiliary support for the decision of the safe construction of tunnel engineering.
