Excavation Face Stability Analysis of EPB Shield in Half-Chamber Tunneling Mode

Excavation Face Stability Analysis of EPB Shield in Half-Chamber Tunneling Mode

［Objective］ In complex geological environments such as soft upper and hard lower or weathered rock layers, during the construction of EPB (earth pressure balance) full chamber tunneling mode, the slag liquid level is too high, the cutterhead generates excessive torque, causing lots of energy consump...
