Abstract: A method for simulating landslide stability based on geophysical exploration data is provided. Electrical resistivity ? of a to-be-detected rock-soil mass in a landslide area is measured. Geophysical exploration data of a landslide profile is acquired and processed, and an electrical resistivity profile is obtained by inversion. The electrical resistivity profile is subjected to interpret partition to obtain a corresponding landslide geological model. A relationship model between shear strength parameters and physical property parameters of a typical rock-soil mass is established. Shear strength parameters of the to-be-detected rock-soil mass are calculated according to the relationship model. A preset condition is loaded into the landslide geological model. A landslide stability numerical simulation result is outputted to evaluate the landslide stability.
