Water pipelines in water diversion projects can leak, leading to soil deformation and ground subsidence, necessitating research into monitoring technology. This study conducted model tests monitor around leaking buried using distributed fiber optic strain sensing (DFOSS) technology based on optical frequency domain reflectometry (OFDR). By arranging measurement fibers a pipe–soil model, we investigated how leak location, size, pipe burial depth, flow velocity affect field results. The results showed that pipeline leakage creates “saddle-shaped” spatial distribution of above the pipeline, effectively indicating subsidence locations. When only one survey line is arranged, it preferable place directly pipeline. Surface primarily detected tensile strain, with more pronounced peak values observed under conditions larger higher velocity, shallow top-pipe location. Monitoring below mainly unimodal distribution, coinciding sequential timing changes at different positions enabled determination seepage direction. demonstrates DFOSS provide important support for early warning such geological disasters.

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.
