Abstract：
Taking the running tunnel from Gangwan square station to Zhongshan square station of Dalian Metro as
background, the control technique and change law of driving parameters are analyzed for shield tunnelling in the mixed strata including full face hard rocks, uneven hard and soft rocks, and uneven weathered rocks. According to this law, the optimization suggestion on driving parameters are given. In light of the grey system theory, GM (1,1) prediction model is introduced to predict the total driving thrust. The results show that the predicted thrust value is close to the actual driving data. It′s explained that using this model the driving parameters in short term can be predicted for shield tunnelling in complex strata.
