| Abstract: | The working principle of electro-hydraulic control system for EPB shield tunnelling machine was expounded.The system model was established in the AMESim environment,and the relationships among the speed of pushing system,rotational speed of screw conveyor and the earth pressure of the closing chamber were also simulated.The simulation results show that the earth pressure can be controlled by controlling the speed of pushing system and the rotational speed of screw conveyor,which can control the ground settlement and guarantee the tunnelling quality. |
