Prediction and calculation of slope stability in Kon Tum, Tay Nguyen, taking into account the amount of precipitation and the creep process of soil

Abstract

Mountainous terrains, and regions subjected to high seismic activities, and extreme heavy rainfall. In recent years, climate changes and unusual natural phenomena have frequently occurred. As a result, the evolution of landslides develops diversely and complexly. In the article, the authors conduct the prediction and slope stability analysis using Plaxis FEM software for the case study in Kon Tum, Tay Nguyen, taking into a great amount of long-duration precipitation, and the creep process of soil. The achieved results provide the actual factor of safety, which is necessary to implement appropriate measures to avoid landslides in wet season.

Keywords: Landslides, unsaturated soil, slope stability, creep, factor of safety.
