The invention relates to a BIM-based grating array track monitoring information visualization analysis method and system. The method comprises the following steps: constructing a track construction BIM model on a monitoring platform; field monitoring points and model monitoring points of the BIM model are arranged, state information of the track structure is monitored through fiber grating sensors arranged at the field monitoring points and sent to a fiber grating demodulator, and the fiber grating demodulator receives the monitoring information sent by the fiber grating sensors and demodulates the monitoring information; and the fiber bragg grating demodulator transmits monitoring information of each field monitoring point to the model monitoring points corresponding to the BIM model in real time, reconstructs, operates and maintains the BIM model, and updates model, information and image visualization results in real time. According to the method, a track is dynamically modified according to monitoring information parameterization to construct a BIM model, a full-life-cycle track digital twinborn model is formed, the model and information are utilized to carry out dynamic analysis, disease analysis, structural analysis and the like, and then visual expression of analysis results is achieved.
