Abstract: Based on the analysis of the correlation between in-situ rock strength and TBM performance, a novel rock strength estimation model was proposed. To ensure the in-situ rock strength more accurately, variations of average TBM performance parameters along the tunnel alignment was analyzed in detail, then the fitting relationship with uniaxial compressive strength(UCS)was established. UCS was estimated rapidly by the field penetration index(FPI)based on regression coefficient R2: 0.761 2(field penetration index, FPI)> 0.759 5(thrust)>0.691 5(specific energy, SE)>0.598 6(torque)>0.561 5(penetration). Compared with the previous works on rock strength estimation, the novel rock strength estimation model is more targeted and applicable. The preliminary results of this study provide a more practical and feasible idea for in-situ rock strength estimation of TBM engineerings.

Key words: in-situ rock strength, estimation model, TBM, boring parameters
