Frost heave and thaw settlement in cold regions poses a significant threat to engineering construction. Optical frequency domain reflectometry (OFDR) based on Rayleigh scattering can be applied monitor ground deformation frozen soil areas, where the interface behavior of soil-embedded fiber optic sensors governs monitoring accuracy. In this paper, series pullout tests were conducted (FO) cables embedded investigate cable‒soil behavior. An experimental study was performed interaction effects, particularly focused water content unfrozen soil, freezing duration, differential distribution soil. The high-resolution axial strains FO obtained using sensing interrogator, then used calculate shear stress. interfacial mechanical response analytically modeled elastic-perfectly plastic softening constitutive models. Three periods, correlating with phase change process between ice water, analyzed. results shows that effect amplify peak stress at cable-soil by eight times. A criterion for coupling states proposed normalizing force‒displacement information. Additionally, applicability existing theoretical models discussed comparing back‒calculations measurements. This provides new insights into progressive failure strain cable which assist interpretation deformation.
