The development of shield tunnelling in China is investigated in the former project,and the results of the comparison between China and other countries demonstrates that there exists some shortages in the construction monitoring and management.In the research project,with the technique application of multimedia collection and transmission,a set of monitoring system has been established.Based on the theories of ground movement during shield tunnelling,the computer code of prediction and control models of ground surface settlement has been developed.With the introduction of volume vision based simulation technique,the prediction and control models are integrated in the simulation software.The monitoring and computer simulation system was tested and calibrated in the tunnelling of Shanghai Metro Line No.2.The practice shows the easy operability and stability of the system.
