Investigating Influence of Freeze-Thaw Cycles on Sandstone Containing Pre-Existing Joints through Discrete Element Modeling
Publication: Geo-Congress 2023
ABSTRACT
In this study, the discrete element method (DEM) is adopted to evaluate the damage and cracking behaviors of sandstone containing two unparallel fissures under freeze-thaw cycles. The rock and water compositions are represented by particles of different sizes and properties, with smaller water particles filled into rock pores. A modified elastoplastic parallel bonded model is developed to describe the accumulation of residual strain caused by the ice-water phase change. The model is calibrated by comparing numerical results [uniaxial compressive strength (UCS), Young’s modulus, and failure pattern] with published experimental data. Compared with published experimental results, similar crack coalescence patterns and similar deteriorating effects of freeze-thaw cycles (FTCs) are observed in the numerical results. This study enhances our understanding of the influence of FTC on the cracking behaviors of sandstone containing fissures and may contribute to the future design and assessment of climate-resilient infrastructure.
