Wear mechanism and life prediction of the ripper in a 9‐m‐diameter shield machine tunneling project of the Beijing new airport line in a sand‐pebble stratum
Abstract Tool wear is a noteworthy problem in the process of shield tunneling, and the degree of wear varies with stratum. The sand‐pebble strata in Beijing are typically mechanically unstable. However, many subways are buried wholly or partially in sand‐pebble strata. Taking the Beijing New Airport...
