Zusammenfassung:	The invention provides a method and system for predicting stratum settlement caused by shield tunneling construction. The method comprises the steps that a space curve shield tunnel calculation model and an overall sinking type model of a shield cross section are constructed according to the tunneling posture of a shield tunneling machine; deriving a final analytic solution of vertical deformation by using a mirror image method based on the space curve shield tunnel calculation model and the overall sinking model; determining an overexcavation gap and a shield tail integration gap according to the final analytic solution of the vertical deformation; and calculating a stratum settlement result by using the overexcavation gap and the shield tail integration gap. According to the method, the space curve shield tunnel calculation model and the overall sinking type model of the shield cross section are constructed through the tunneling posture of the shield tunneling machine, stratum settlement prediction is compl
