The invention discloses a non-interference optical fiber intelligent monitoring device and method for a sliding type dangerous rock mass, and the device comprises a data collection unit, a data monitoring unit, and a data processing unit, which are connected in sequence. The advanced optical fiber sensor technology is adopted to monitor the lower edge structural surface of the sliding type dangerous rock mass block in real time, and then interference-free real-time monitoring on the sliding type dangerous rock mass block is achieved. 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 deformation condition of the sliding type dangerous rock body lower edge structural face, and then whether a sliding type dangerous rock body will be subjected to instability damage or not is judged. According to the invention, 24-hour uninterrupted automatic real-time monitoring can be realized, the device can
