Transfer type monitoring method for vault settlement in tunnel operation period

The invention relates to the technical field of engineering measurement deformation monitoring, in particular to a transmission type monitoring method for vault settlement in a tunnel operation period, and the method comprises the steps: firstly constructing an early warning system which comprises a data collection end and an early warning center; the data acquisition end comprises an initial reference point target, an automatic monitoring unit, a dangerous section vault monitoring target and a transmission reference point target which are fixed at a deep buried section, and a deep buried stable section reflective target is used as an initial reference point, and the side wall fixed type automatic monitoring unit and the transmission reference point are arranged at intervals in a crossed manner; and monitoring vault settlement of the vault measuring points of dangerous sections such as the shallow buried section and the open cut tunnel section relative to the reference point according to the displacement of t
