Application of Virtual Reality Technology to Shield Tunnelling in Karst Areas
(1. China Railway Engineering Equipment Group Mechanical and Electrical Engineering Co., Ltd., Chengdu 610036; 2. State Key Laboratory of Resource and Environmental Information Systems, Institute of Geographic Sciences and Natural Resources Research,CAS, Beijing 100101; 3. College of Mechanical Engineering, Southwest Jiaotong University, Chengdu 610031)
Abstract This study utilizes 3DMAX to establish a model base of tunnels built by the shield tunnelling method,
and creates a panoramic display of the construction site by Unity3D engine technology and virtual reality hardwares on the basis of geological investigation data and advanced geological prediction results. The actual application of this technology to shield tunnelling in karst areas demonstrates that: in advanced geological prediction for shield tunnelling, virtual reality technology can directly show the spatial form of tunnel strata to non-geologist users,reduce the need for communication among the personnel, dispaly the geological information and advanced prediction results of the tunnel area in a clear, three-dimensional and dynamic way, and provide a large amount of geological information for shield tunnelling in time, thus increasing the safety of tunnel construction.
