In this paper, the shield tunneling parameters in different geological sections are summarized; the multiple regression analysis is made on advancing speed and cutterhead torque of shield; the regression model of shield tunneling parameters in complex strata is obtained; and the relationship between parameters of regression models and the fullface equivalent basic quality index of rock mass is studied. The study results show that: 1) The fullface equivalent basic quality index of rock mass with consideration of proportion of different geological conditions can take as standards for geological sectioning. 2) The difference between predicted advancing speed and cutterhead torque of shield and measured data is little. The regression models have a good adaptability to homogeneous or complex strata. 3) The parameters of regression models, shield advancing speed and cutterhead torque, have obvious sectioned characteristics when the surrounding rock grade increases. The quantified results can be applied to predict shield advancing parameters in different strata and improve shield tunneling efficiency.
