Pressure control model on soil chamber of shield machine and its parameter identification
Abstract：The pressure control model on soil chamber of shield machine was proposed based on nonlinear constitutive relationship between stress and strain of conditioned soil in soil chamber of shield machine. The parameter identifica- tion procedure of pressure control model was presented according to in-situ observed pressure on soil chamber, rotating speed of screw conveyor and thrusting speed of shield machine. The practical application of proposed procedure shows that proposed pressure controX model and parameter identification procedure are very effective, and forecasted pressure on soil chamber agrees well with observed ones.
