Abstract: Disclosed are a joint landslide monitoring system and method. The system includes: a high-frequency electromagnetic wave monitoring module configured to continuously emit electromagnetic wave signals into a monitoring area, perform interference processing on signals received by a receiving antenna to obtain target signals, and obtain surface deformation information of the monitoring area according to a phase difference of the target signals; a low-frequency seismic wave monitoring module configured to propagate seismic waves downward from a ground surface in the monitoring area, receive reflected waves from a creeping medium that the seismic waves encounter, obtain frequency-domain interference characteristics of internal creeping; and determine a longitudinal force on a 3D stratigraphic landslide mass shear surface; and a cloud platform configured to determine a maximum subsidence amount and a subsidence velocity of the monitoring area, and issue alert information when the maximum subsidence amount or the subsidence velocity exceeds a preset range.
