Abstract The paper applies a method of multi rings to determine positions of erection points of the uni
versal rings , and to decide the correction lines based on the geometric features of the rings and the designed
tunnel axis in shield tunnels A virtual erection system of the rings is developed based on Unigraphics The
system is used to simulate the dynamic erection , manage data of ring erection and generate the report of the
erection deviations This system has been applied in a shield tunnel with giant diameter in Shanghai The
result verifies the usability of the system
Key words shield tunnel ; universal rings ; rings erection ; key position ; corrections
