Abstract:

The initial precision of orienting system is very important for shield tunneling. The initial precision of ROBOTECorienting system is low after shield tunneling for several times, even worse, wrong initial data would be obtained. The initial precision of orienting system is improved by means of shield hull monitoring and 3D rotating method. 
