Shallow-buried tunnel construction dynamic control method based on three-dimensional live-action numerical analysis

The invention discloses a shallow tunnel construction dynamic control method based on three-dimensional live-action numerical analysis. Real geological conditions of a tunnel field are restored by adopting live-action modeling and three-dimensional geological model construction technologies. And calculating a deformation value in the tunnel construction process by adopting a numerical analysis method based on the live-action geological model. In the construction process, calculation parameters of the numerical model are inverted along with updating of monitoring data, and therefore the stress distribution condition of the shallow tunnel field is accurately calculated. And running the corrected numerical analysis model, predicting a deformation value of the next stage of tunnel construction, continuously optimizing the numerical analysis model in combination with monitoring data, performing early warning in advance, and performing early warning if a predicted value exceeds a limit and a predicted value allowab
