Numerical analysis for rock cutting force prediction in the tunnel boring process

Study of rock cutting force prediction is of great significance for improving the efficiency of rock breaking and optimizing the tunnel boring process. A new prediction model named RCC (the Roxborough Model and the CSM Model and the Colorado School of Mines’ Data Integration) model is proposed to predict vertical, rolling and lateral forces acting on the disc cutter based on the theoretical model developed by Roxborough and Phillips (1975)...
