Abstract：Based on numerical simulation by using finite element method, the reference model was proposed for controlling earth pressure of head chamber. The relationship between the strain and the accumulating amount of earth was proposed based on Duncan and Chang's model. The relationship between the increment of earth pressure and the angular velocity of screw conveyor was presented. The controlling model of earth pressure balance of shield machine was proposed with optimization algorithm. The numerical simulation shows that the proposed control model is effective and stable for controlling earth pressure of shield machine by adjusting speed of screw conveyor.
