Tóm tắt:

Landslides are a very common form of natural disasters in Vietnam with diverse scales, complex triggers, and mechanisms. The greatest objective of the landslide studies is zoning and predicting, and therefore, a combination of appropriate, modern study methods are needed. This study presents the results of time-variant slope stability analysis by combining the limit equilibrium method with geospatial data. The slope stability analysis was conducted at six times, with the variation of pore water pressure ratio, ru corresponding to the change of rainfall in the study area. The results of the study have helped restore the landslide scenario in Cao Thang, Ha Long, and evaluated the landslide trigger. This model can also be used for slope stability analysis and landslide prediction for early warning, management, and urban planning.
