Study on mechanical properties of rock and soil mass in the slip zone of shibanping landslide

Frontiers in Earth Science
The mechanical behavior of landslide rock masses and slip zone soils plays a crucial role in the initiation and evolution of landslides, particularly under prolonged rainfall conditions, where the saturation process leads to strength degradation and ...

Damage cause and mechanism of well-vegetated soil slopes under extreme rainfall: a case study

Frontiers in Earth Science
A substantial number of shallow landslides can still occur in areas with high vegetation cover under extreme rainfall. The cause and mechanism of this type of landslide remain unknown, and thus a case study is selected for study in this paper.

Burgers-type empirical creep model for unsaturated soil considering matric suction

Shenzhen Daxue xuebao. Ligong ban
Reservoir bank slopes are often in an unsaturated state due to water level fluctuations and atmospheric precipitation, which can easily trigger landslides. Therefore, it is necessary to develop a creep model for unsaturated soils that accounts for matric
