Abstract

Shield tunneling technologies have been developed for constructing tunnels in soft ground especially with groundwater. However, the automatic deviation correction systems are based on empirical relationships or theoretical model including a great deal of unknown parameters. In this paper, the shield-segment system is considered as underground parallel manipulators, so the shield behavior can be represented by the rotation of motion platform around the static platform. Consequently, load model acting on the shield is developed based on the proposed relationship between the shield behavior and the ground displacement. The examples of straight alignment and curve alignment were studied, comparing the results with the others model, and the results validate the load model studied here.
