The invention discloses a soil
landslide monitoring, early warning and evaluating method which comprises the following steps: S1, acquiring
landslide topography and geological data to be monitored, and acquiring a rock-soil parameter test value through an indoor test; S2, establishing a
landslide geologic model, carrying out
limit analysis, determining a landslide damage mode and carrying out landslide monitoring; S3, uniformly designing parameter combinations for the rock-soil parameter test values, performing finite element calculation on all the parameter combinations to obtain a
displacement field calculated by each parameter combination, and recording the displacement of each monitoring point to obtain a 'parameter combination-displacement' neural
network model; S4, according to the landslide real-time cumulative displacement
monitoring data and the parameter combination-displacement neural
network model, performing rock-soil parameter inversion correction, obtaining rock-soil real-time strength parameters, and performing precision inspection; and S5, performing
limit analysis by adopting real-time strength parameters, establishing a 'real-time cumulative displacement-
safety coefficient' relation curve, establishing a landslide monitoring three-level early warning grade
evaluation system, and evaluating the monitored landslide.
