Based on the natural moisture content and density test, specific gravity test, grain size analysis tests, water content limits test, compaction test and tri-axial consolidated undrained shear test of remodeling sample of sliding soil under different shear rates for the sliding zone soil of a landslide in Badong area, we explore the change trend of shear strength parameters of the sliding zone soil under different shear rates, analyze the stressstrain relations of the sliding zone soil samples, reveal the physical and mechanical characteristics of sliding soil and its effects on the landslide, hoping to offer valuable basic recommendations for the prevention and cure of this type of landslides.
