Abstract This paper discribes the study on the rings prediction in construction of longdistance tunnel shield, a rings prediction model based on coordinate transformation and plane fitting is established,and a computer analysis system is then established for the model as well. In the end, through the analysis of a practical case in Shanghai Cross Yangtze Rive Tunnel, the model is proved to be feasible and can give the good results in quicklyrectifying deviations.
Key words ：
tunnel shield
