Data monitoring method and system for continuous rigid frame bridge

The invention discloses a data monitoring method and system for a continuous rigid frame bridge, and relates to the technical field of continuous rigid frame bridge monitoring. The method comprises the following steps: acquiring first monitoring data of a main beam in the continuous rigid frame bridge, second monitoring data of a pier beam and an environment monitoring index of the position; determining the horizontal displacement, the longitudinal displacement and the inclination angle of the continuous rigid frame bridge according to the first monitoring data of the main beam and the second monitoring data of the pier beam; determining a relative offset value of the continuous rigid frame bridge according to the horizontal displacement, the longitudinal displacement and the inclination angle; calculating a relative change curve between the relative deviation value and the environment monitoring index; and generating a bridge monitoring result of the continuous rigid frame bridge in a preset period according
