| Abstract: | Shield machine is the main mechanical equipment for city subway and tunnel construction. Various parameters of the shield machine impact on the speed and quality of construction. This paper starts with the analysis of shield cutter head torque and rotational speed, the jack thrust, the thrust speed, the speed of screw conveyor and grouting pressure, the flow speed and pressure, the mud and foam flow speed and pressure parameters. The influence of various parameters on the boring performance is analyzed in detail. And then the construction of Beijing subway is as an example, the concrete design strategy for the parameters optimization realization is presented, which will provide theoretical guidance for the construction of scientific organization and management optimization. |
