| Abstract: | 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. |

| Keywords: | sliding zone soil consolidated undrained shear shear rate shear strength stress-strain
