CORRELATION OF LABORATORY CUTTING DATA WITH TUNNEL-BORING MACHINE PERFORMANCE

Results of rock-cutting experiments conducted under constant normal force and constant penetration are discussed. Independent as well as interacting groove-spacing regions are identified and classified through determination of optimum and critical spacings. Specific energy, muck for the independent and interacting grooves of laboratory cutting are examined, and forward thrust, torque, advance rate, and much size distribution in field operations are presented and presented and discussed. Satisfactory correlation is obtained between laboratory cutting resutls and field performance data. /Author/
