| 英文摘要 | Assessing stability and safety of loess slopes requires understanding their anisotropic deformation characteristics across various depths, which is influenced by external disturbances and water infiltration. A major challenge in this field has been lack of reliable detection equipment. Therefore, we developed a detection equipment for anisotropic deformation in slopes. This equipment operates on displacement control to simultaneously measure deformation and pressure at same depth in different directions, capturing anisotropic mechanical properties of loess. After fabrication and debugging, a precision calibration platform was constructed for detection equipment. Then, calibration tests showed a compression deformation precision of 0.28 % F & sdot;S and a compression force precision of 0.47 % F & sdot;S. Finally, field tests involved drilling two 150 mm diameter holes and performing in-situ mechanical property measurements at three depths, validating the equipment's effectiveness for anisotropic detection in loess. This equipment offers new method for exploring anisotropic deformation in slopes. |
