Description

technical field

[0001] The invention relates to the technical field of landslide prevention and control, in particular to a large-area three-dimensional slope stability modeling method based on GIS. Background technique

[0002] Landslides are one of the major natural disasters with huge and widespread impacts around the world and cause human and socio-economic losses. The spatiotemporal prediction of landslide risk still has great uncertainty, and landslide sensitivity assessment is very important for the identification of landslide risk.

[0003] Landslide susceptibility is the spatial probability of landslide occurrence based on local topographic conditions, and landslide susceptibility can be determined using statistical and physics-based models. The most common is the spatial probability of shallow landslides in small watersheds, this modeling relies on the use of a physics-based deterministic model, based on the concept of limit equilibrium resulting in a factor of sa...
