Study on the Shear Strength Parameters under Different Freezing and Thawing Cycles of Soil Slope in China
In seasonal frozen regions, shallow landslide hazards in soil slopes usually happen. The type of failure surface is always on the freezing and thawing surface in the soil slope. So the direct influence factor of soil slope failure is the soil shear strength of the freezing and thawing (F-T) surface. The shear strength of the soil is determined by the two parameters of Cohesion c and Friction angle φ. In this study model experiment of F-T soil interface with different aggregate materials is designed by alternating the F-T cycle times, then the parameters c and the φ were obtained. Finally the deterioration modal of the two shear strength parameters of soil interface was put forward. The results demonstrated when the slope stability in the seasonal frozen regions was analyzed using shear strength reduction method, the two deterioration modals can provide the data reference for the analysis.
