Abstract

The TBM are equipped with electronic in- strumentation that allows measuring and recording the parameters that control the working of the machine. A statistical analysis was carried out on the data, collected in the Route 9 of the Underground of Barcellona, with the aim to study the behaviour of the machine in connection with the geology and with others factors of concern. On the basis of the data colleted was car- ried out the assessment of the cutting speed of the TBM at the given time on given the data collected in the preceding time intervals. This inference, based on the Bayes theo- rem, allows to fit the assesment both to the data collected in the last times and the data collected during the complete story of the excavation. In such a way one obtains the distribution of probability of the influence of the work- ing parameters of the TBM on the penetra- tion speed. This knowledge allows the operator to con- trol the TBM.
