Macro-micro damage model of the effect of freeze–thaw on jointed rocks considering compaction deformation
H Chen, C Zhao, R Zhang, J Xing, L Huang… - Engineering Failure …, 2023 - Elsevier
Jointed rock mass contains microscopic cracks, joints and other defects. Moisture migration
during freeze–thaw cycles affects crack initiation and propagation of defects of different
scales. The change of defects in turn affects the mechanical and deformation properties of
jointed rock mass, especially in the compaction deformation stage. Considering the effects of
freeze–thaw cycles on compaction deformation, plastic deformation, macroscopic damage
and microscopic damage, a macro–micro damage constitutive model of jointed rock mass …
