Abstract:
In the process of shield tunneling in complex formation, shield machine often has problems such as reduced tunneling efficiency and tool failure due to excessive tool wear. Based on the disc cutter wear data of Baiying section of Shenzhen Metro Line 13, a practical prediction method of disc cutter wear was proposed according to Rabinowicz abrasive wear calculation model. The method combined the slip rate calculation formula, the cutter head torque and cutter head thrust to obtain the sliding distance of the disc cutter. The normal load of contact surface was determined by combining the Colorado School of Mining Model(CSM Model), rock strength parameters and the penetration depth of the disc cutter, and the material strength was determined according to the design parameters of the disc cutter. By determining three main factors(sliding distance, normal load of contact surface and material strength)affecting disc cutter wear, the calculation formula of disc cutter wear volume considering shield machine was derived, and the measured wear volume of disc cutter and the predicted wear volume of disc cutter in composite stratum section of Baiying section of Shenzhen Metro Line 13 were compared and verified. The results show that the measured wear volume is in good agreement with the prediction values, which verifies the rationality of the proposed prediction method of cutter wear volume. The research results can provide a theoretical basis for the prediction of cutter wear volume and the determination of cutter change time in composite strata.
