Abstract:The unstable slope body has complex terrain, large slope, mixed topsoil and stone, and developed rock fissures in the lower part, which makes it difficult to detect. There is a lack of effective geophysical exploration means to accurately delineate the distribution position and spatial occurrence state of the unstable slope body. In geological hazard survey in a certain area, the range of unstable slope is delineated by using comprehensive geophysical method ultrahigh density electrical method and micro motion detection. The comprehensive geophysical method accurately infers the distribution position and spatial occurrence state of unstable slope body, and geophysical inference result is basically consistent with the drilling exposure. It is showed that comprehensive geophysical method can effectively delineate the scope and spatial occurrence of geological hazards in the exploration of geological hazards on unstable slopes, which has high reliability and lays a good foundation for the treatment of geological hazards.
