The invention provides a shield tunneling parameter prediction method and system, and relates to the field of shield tunneling parameter prediction. The shield tunneling parameters are predicted and analyzed, the shield tunneling state is further given, the shield construction quality is improved, and the disturbance influence of shield construction on the stratum is reduced. The method comprises the following steps: acquiring shield tunneling parameters, and preprocessing the shield tunneling parameters; any preprocessed tunneling parameter is used as an independent variable, other tunneling parameters are used as dependent variables, and a grey correlation analysis model is established based on the independent variable and the dependent variables so as to determine the sensitivity relation between data in the dependent variables and the independent variable; based on a Pearson's correlation coefficient method, measuring a correlation degree between data in the independent variable and the dependent variable
