The simulation and prediction of shield boring parameters in complex strata are still in weak positions. The boring performance of EPB shields in the complex strata in DashiHanxi running tunnel on No. 3 line of Guangzhou Metro is simulated and analyzed by means of Terzaghi loose soil pressure model and CSM model. The simulation results coincide with the actual boring performance, except that there are great differences between the simulated thrust and torque values and the measured values when boring in hard rocks with 20mm/r penetration rate. The causes for the differences are analyzed. The thrust and torque when boring in complex ground with soft and hard rocks are calculated. The simulation results show that the simulated total thrust and torque are within the range of the measured values. The effectiveness of the mentioned simulation and calculation method is verified.
