Hydraulic projects with dispersive soil in seasonally frozen regions are susceptible to landslide failures.
The mechanism of such landslide failures has not been fully understood thus far; therefore, it was investigated in this study by using on-site surveys, laboratory tests, and theoretical calculations.
The results showed that the landslides of dispersive soil in seasonally frozen regions could be categorized as shallow-seated landslides and deep-seated landslides.
The preconditions for landslide occurrence were soil mass looseness and cracks, caused by freeze-thawing.
The degradation of dispersive soil led to a rapid influx of water into the soil.
The reason for shallow-seated landslides was that the numerous sodium ions present in the soil mass dissolved in water and damaged the soil structure, resulting in a substantial reduction in shear strength.
The reason for deep-seated landslides, however, was the erosion due to rainfall infiltration after the shallow-seated landslides caused tensile cracks at the top of the slope, leading to soil instability.
Landslide failures occurred when the dispersing soil slope underwent freeze-thawing and saturated soaking.
The sliding surface was initiated at the top of the slope and gradually progressed to the bottom along the interface between the soil layers.
