Abstract：According to the features of control in shield adjacent construction，the control model of the whole process—APLOC has been established based on IMC-PID controller with consideration of the effects of earth balance pressure at workface and shield tail grouting parameter on ground deformation. The influences of the earth pressure and the grouting parameter on the ground and the adjacent tunnel settlement have been studied and analyzed by APLOC. Simulation results show that the proposed controller model has the features of excellent stability and robustness. The maximum settlement of the adjacent tunnel is successfully controlled within 5 mm making use of this control model.
