An enhancement to pre & post processing techniques, which is encapsulated in ‘Tunnel Modelling Wizard (TMW)’ for three dimensional tunnel analysis, is developed and described in this paper. The techniques include geometry modelling, mesh generation, virtual transformation, flying view and utilization and interpretation of analysis results. The TMW automatically generates full analysis data including mesh, loads, boundary conditions and construction stages from the user-defined parameters. The TMW also provides its own file I/O service to help users expedite modelling tasks for similar models and build their own tunnel templates. Implementation of the TMW into a FE Program is described, and applications of the TMW to practical tunnel problems will be demonstrated.
