文摘

We categorized factors influencing tool wear in EPB-TBM tunneling. We analysis effect of TBM operational parameters and geological factors on tool wear. We analysis cutter life for EPB machine. We found that soil conditioning, earth pressure, machine torque, thrust, penetration rate and rpm greatly reduce tool wear. Improving soil conditioning parameters reduces tool wear even in coarse-grained soils.
