Platform early warning evaluation method suitable for enclosure rock-entering working condition

The invention relates to a platform early-warning evaluation method suitable for an enclosure rock-entering working condition, and the method comprises the following steps: collecting actual inclination measurement data of a foundation pit enclosure wall, and recording the actual inclination measurement data as a data group 1; geological parameters, working condition parameters and mechanical parameters of foundation pit excavation are input into the elastic foundation beam model to calculate the inclination survey simulation data of the enclosure wall in the foundation pit excavation stage, and the data are recorded as a data set II; the actual bending moment of the whole enclosure wall is calculated through the inclination measurement deformation curvature of the enclosure wall; and calculating a bending moment safety margin of the enclosure wall according to the actual bending moment of the enclosure wall and the ultimate bending moment of the section, judging whether the bending moment safety margin of th
