Updating the Decision Aids for Tunneling

摘要: The “Decision Aids for Tunneling” are a procedure and computer code that can be used to assess the effect on construction cost time of geologic/geotechnical uncertainties in process. Previously, it was only possible make predictions prior construction. There is, however, need updated while is progress. Such improve scheduling, resource allocation, financial planning, so on. This article presents an updating allows one refine during Updating not involves replacing original prediction with actual data from excavation, but also includes learning component using information excavation arrive at improved unexcavated part tunnel.
