The invention discloses an optical fiber intelligent monitoring device and monitoring method for deformation of a sliding type dangerous rock mass block, and the device comprises a data collection unit, a data monitoring unit and a data processing unit which are sequentially connected. The advanced optical fiber sensor technology and the anchoring and supporting technology are combined, the interior of the sliding type dangerous rock mass block is monitored in real time, and meanwhile anchoring and supporting treatment measures are taken for the sliding type dangerous rock mass. The device has the advantages of being small in size, high in precision, low in power consumption and the like, data processing and error correction can truly reflect the situation of internal deformation of the sliding type dangerous rock mass, and whether deformation of the sliding type dangerous rock mass is within a safe range or not is judged. According to the invention, 24-hour uninterrupted automatic real-time monitoring can be
