| 英文摘要 | Soil frost deformation significantly influences engineering projects in cold regions. The anisotropic behavior of soil, involving surface and internal deformation in three dimensions (3D), introduces inaccuracies in evaluating freeze-thaw geological hazards. To explore the relationship between internal strain and surface displacement of soil in a 3D space during the freezing -thawing process, a platform for monitoring coupled surface -internal deformation in 3D were developed using binocular recognition technology and a novel 3D strain rosette. Subsequently, a freezing -thawing model test of soil in Dalian Offshore Airport filling is conducted using the platform. The results show that, the internal strain of soil is closely associated with the boundary conditions of the test unit. During freezing test, the vertical strain exhibits a more significant increase in comparison to the horizontal strain. Surface displacements in soil primarily occur during the initial freezing and thawing stages. The variation of surface horizontal displacement in each direction is minimal throughout the freezingthawing process. A surface freezing boundary leads to an increment in internal strain, while the deep frozen stress relief causes the soil surface expand during thawing. This study provides a suggestion for the control of the cold source in cold region engineering. (c) 2023 Production and hosting by Elsevier B.V. on behalf of The Japanese Geotechnical Society.
