摘要
The TBM Excavation Control System developed by authors has already been put to practical use. It can monitor the drill energy coefficient calculated from the drill logging data as an index of rock properties and the TBM driving data during the excavation. In this paper, the new TBM risk management system is developed to realize the automatic, real-time prediction of the rock properties ahead of the tunnel face with good precision. The core feature of this system is to analyze data by means of the geostatistical methods such as the Kriging and the Sequential Indicator Simulation. It allows us to use outputs as a form of risk management. This system is put into practical use and validated in the ongoing construction site.
