摘      要：This research explores the potential for the evaluation and prediction of earth pressure balance shield performance based on a gray system *** research focuses on a shield tunnel excavated for Metro Line 2 in Dalian,*** to the large error between the initial geological exploration data and real strata,the project construction is extremely *** view of the current situation regarding the project,a quantitative method for evaluating the tunneling efficiency was proposed using cutterhead rotation(R),advance speed(S),total thrust(F)and torque(T).A total of 80 datasets with three input parameters and one output variable(F or T)were collected from this project,and a prediction framework based gray system model was *** on the prediction model,five prediction schemes were set *** error analysis,the optimal prediction scheme was obtained from the five *** parametric investigation performed indicates that the relationships between F and the three input variables in the gray system model harmonize with the theoretical *** case shows that the shield tunneling performance and efficiency are improved by the tunneling parameter prediction model based on the gray system model.
