    Abstract:

    [Objective] Exploring the influence of shearing method on the residual strength of remolded loess in order to provide a scientific basis for the evaluation and treatment of loess landslide engineering.[Methods] To explore the influence of different shear modes on peak strength, residual strength and deformation, ring shear test was carried out on Jingyang loess by ring shear apparatus.[Results] The peak strength and residual strength of remolded loess increased with the increase of effective normal stress, and the greater the effective normal stress, the easier the loess to achieve the residual strength. The deformation of remolded loess is shown as shear compression. The average value of residual strength index obtained by single-stage shear and multistage shear was close.[Conclusion] The shear method is recommended for single-stage shear.
