Sensor optimized arrangement-based landslide line early-stage form determining method

The invention discloses a sensor optimized arrangement-based landslide line early-stage form determining method. The method includes the following steps that: step 10) landslide line estimated line form is determined; step 20) a target monitoring point is determined on the landslide line estimated line form; step 30) the attenuation calculation radius of acoustic emission signals of mountain acoustic emission sources is determined; step 40) acoustic emission sensors or shared acoustic emission sensors are arranged around the target monitoring point; and step 50) a monitoring data receiving device is utilized to receive and analyze acoustic emission signals acquired by the acoustic emission sensors or shared acoustic emission sensors, and the acoustic emission sources are connected together so as to be adopted as the early-stage form of a landslide line. According to the determining method, the arrangement of the sensors is optimized, and a maximized monitoring range can be realized with a small number of sens
