| Abstract: | In order to control ground settlement and reduce ground deformation, thrust hydraulic system and screw conveyor hydraulic system of shield tunnelling machine were designed with electro-hydraulic proportional control technology. Proportional pressure and flow compound control technology was applied in the thrust hydraulic system, and electric feedback proportional control technology was applied in the screw conveyor hydraulic system. Experimental analysis was also carried out on a simulator test rig. The experimental results showed that the earth pressure can be controlled within the range of set values by realtime controlling thrust speed or revolving speed of screw conveyor, which can realize thrust control or discharge control for shield tunnelling machine. Finally, the earth pressure balance is realized. |
