Frost deformation and microstructure evolution of porous rock under uniform and unidirectional freeze-thaw conditions
Abstract The frost deterioration and deformation of porous rock are commonly investigated under uniform freeze-thaw (FT) conditions. However, the unidirectional FT condition, which is also prevalent in engineering practice, has received limited attention. Therefore, a comparative study on frost defo...

| 520 | |a Abstract The frost deterioration and deformation of porous rock are commonly investigated under uniform freeze-thaw (FT) conditions. However, the unidirectional FT condition, which is also prevalent in engineering practice, has received limited attention. Therefore, a comparative study on frost deformation and microstructure evolution of porous rock under both uniform and unidirectional FT conditions was performed. Firstly, frost deformation experiments of rock were conducted under cyclic uniform and unidirectional FT action, respectively. Results illustrate that frost deformation of saturated rock exhibits isotropic characteristics under uniform FT cycles, while it shows anisotropic characteristics under unidirectional FT condition with both the frost heaving strain and residual strain along FT direction much higher than those perpendicular to FT direction. Moreover, the peak value and residual value of cumulative frost strain vary as logarithmic functions with cycle number under both uniform and unidirectional FT conditions. Subsequently, the microstructure evolution of rock suffered cyclic uniform and unidirectional FT action were measured. Under uniform FT cycles, newly generated pores uniformly distribute in rock and pore structure of rock remains isotropic in micro scale, and thus the frost deformation shows isotropic characteristics in macro scale. Under unidirectional FT cycles, micro-cracks or pore belts generate with their orientation nearly perpendicular to the FT direction, and rock structure gradually becomes anisotropic in micro scale, resulting in the anisotropic characteristics of frost deformation in macro scale. | ||

Under uniform FT cycles, newly generated pores uniformly distribute in rock and pore structure of rock remains isotropic in micro scale, and thus the frost deformation shows isotropic characteristics in macro scale. Under unidirectional FT cycles, micro-cracks or pore belts generate with their orientation nearly perpendicular to the FT direction, and rock structure gradually becomes anisotropic in micro scale, resulting in the anisotropic characteristics of frost deformation in macro scale.

However, the unidirectional FT condition, which is also prevalent in engineering practice, has received limited attention. Therefore, a comparative study on frost deformation and microstructure evolution of porous rock under both uniform and unidirectional FT conditions was performed. Firstly, frost deformation experiments of rock were conducted under cyclic uniform and unidirectional FT action, respectively. Results illustrate that frost deformation of saturated rock exhibits isotropic characteristics under uniform FT cycles, while it shows anisotropic characteristics under unidirectional FT condition with both the frost heaving strain and residual strain along FT direction much higher than those perpendicular to FT direction. Moreover, the peak value and residual value of cumulative frost strain vary as logarithmic functions with cycle number under both uniform and unidirectional FT conditions. Subsequently, the microstructure evolution of rock suffered cyclic uniform and unidirectional FT action were measured. Under uniform FT cycles, newly generated pores uniformly distribute in rock and pore structure of rock remains isotropic in micro scale, and thus the frost deformation shows isotropic characteristics in macro scale.

However, the unidirectional FT condition, which is also prevalent in engineering practice, has received limited attention. Therefore, a comparative study on frost deformation and microstructure evolution of porous rock under both uniform and unidirectional FT conditions was performed. Firstly, frost deformation experiments of rock were conducted under cyclic uniform and unidirectional FT action, respectively. Results illustrate that frost deformation of saturated rock exhibits isotropic characteristics under uniform FT cycles, while it shows anisotropic characteristics under unidirectional FT condition with both the frost heaving strain and residual strain along FT direction much higher than those perpendicular to FT direction. Moreover, the peak value and residual value of cumulative frost strain vary as logarithmic functions with cycle number under both uniform and unidirectional FT conditions. Subsequently, the microstructure evolution of rock suffered cyclic uniform and unidirectional FT action were measured. Under uniform FT cycles, newly generated pores uniformly distribute in rock and pore structure of rock remains isotropic in micro scale, and thus the frost deformation shows isotropic characteristics in macro scale. Under unidirectional FT cycles, micro-cracks or pore belts generate with their orientation nearly perpendicular to the FT direction, and rock structure gradually becomes anisotropic in micro scale, resulting in the anisotropic characteristics of frost deformation in macro scale.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Frost deformation</subfield><subfield

frost deformation and microstructure evolution of porous rock under uniform and unidirectional freeze-thaw conditions |

Frost deformation and microstructure evolution of porous rock under uniform and unidirectional freeze-thaw conditions |
| abstract |
Abstract The frost deterioration and deformation of porous rock are commonly investigated under uniform freeze-thaw (FT) conditions. However, the unidirectional FT condition, which is also prevalent in engineering practice, has received limited attention. Therefore, a comparative study on frost deformation and microstructure evolution of porous rock under both uniform and unidirectional FT conditions was performed. Firstly, frost deformation experiments of rock were conducted under cyclic uniform and unidirectional FT action, respectively. Results illustrate that frost deformation of saturated rock exhibits isotropic characteristics under uniform FT cycles, while it shows anisotropic characteristics under unidirectional FT condition with both the frost heaving strain and residual strain along FT direction much higher than those perpendicular to FT direction. Moreover, the peak value and residual value of cumulative frost strain vary as logarithmic functions with cycle number under both uniform and unidirectional FT conditions. Subsequently, the microstructure evolution of rock suffered cyclic uniform and unidirectional FT action were measured. Under uniform FT cycles, newly generated pores uniformly distribute in rock and pore structure of rock remains isotropic in micro scale, and thus the frost deformation shows isotropic characteristics in macro scale. Under unidirectional FT cycles, micro-cracks or pore belts generate with their orientation nearly perpendicular to the FT direction, and rock structure gradually becomes anisotropic in micro scale, resulting in the anisotropic characteristics of frost deformation in macro scale. © Science Press, Institute of Mountain Hazards and Environment, CAS and Springer-Verlag GmbH Germany, part of Springer Nature 2024 |
