Summary and outlook

  • Gernot Beer


In this book the main results of the Austrian joint research initiative Numerical Simulation in Tunnelling have been presented. The main aim of this research work was to advance the reliability and efficiency of existing numerical simulation methods. To achieve an increase in reliability of the methods, i.e. to ensure that predictions made agree well with actual behaviour a significant amount of development had to be made with respect to material models for rock/soil and shotcrete as well as with respect to the material parameters used. To increase the efficiency of the methods and to make the methods usable for tunnel engineers the input of data to the simulation program has to be made automatic to a great degree. Meshes that are necessary for the numerical simulation need to be generated completely automatic. An essential part of this development was improvements in the acquisition of geological data. The new method of data acquisition developed means that the information can be obtained in digital form and fed directly into the pre-processing software for the numerical simulation program.
