In cold regions, the extensive distribution of silt exhibits limited applicability in engineering under freeze–thaw cycles. To address this issue, study employed rice husk carbon and calcium lignosulfonate to stabilize from areas. The mechanical properties stabilized conditions were evaluated through unconfined compressive strength tests triaxial shear tests. Additionally, scanning electron microscopy was utilized analyze mechanisms behind stabilization. Ultimately, a damage model for carbon–calcium constructed based on Weibull function Lemaitre’s principle equivalent strain. findings indicate that as content increases, rate improvement progressively accelerates. With an increase number cycles, deviatoric stress soil gradually diminishes; decline peak becomes more gradual, while reduction cohesion intensifies. decrease angle internal friction is relatively minor. Microscopic examinations reveal cycles pores tend enlarge multiply. established applied loads demonstrates similar pattern between experimental theoretical curves four different confining pressures, reflecting initial rapid followed by steady trend. Thus, it evident outperforms traditional constitutive models, offering accurate depiction variations observed.
