Evaluation of the Adaptability of an EPB TBM to Tunnelling

The equation commonly used to predict the total thrust of an EPB TBM is where Fs is an empirical coefficient with a value within 700–1,200 kN/m 2 and De is the excavation diameter [ 37 ]. Based on the known value of De = 6.980 m, the adaptability range of the total thrust was determined to be 26,785–45,918 kN.
