This study addresses the risks arising from the inherent geological variability and ground uncertainties that affect the face stability during tunnel boring machine (TBM) operations. It used the data from Kolkata East–West Metro UG-1 Package to predict the relationships between the tunnel face stability and the properties of soils ahead of the TBM. It considered the cutterhead-soil interaction during the mechanised shield tunnelling and used the load transferred from the tunnel face to the cutting wheel as input. A statistical multi-parametric regression and hypothesis testing were then done on the modified relationships. These correlations can reasonably assess, in real-time, the in situ properties ahead of the TBM for the prediction of tunnel face stability. The application could optimise the operational cost by bringing in a degree of automation in the TBM operations, by assessing the face support pressure as function of the boring parameters.
