Red sandstone is widely distributed in southern China. Due to the significant difference mechanical properties before and after hydration its poor water stability, red often triggers landslide accidents. In this paper, from an open pit slope Jiangxi Province was taken as research object. Two variables, namely initial saturation degree (25%, 50%, 75%, 100%) number of wetting–drying cycles (0, 10, 20, 30, 40), were set. With help nuclear magnetic resonance, Brazilian disc test, fractal theory, relationships among meso-structure, macroscopic fracture mechanics characteristics, deterioration mechanism analyzed. The results are follows: (1) Wetting–drying have a impact on pore structure characteristics sandstone. Moreover, higher degree, more obvious effect rock mass. (2) After further subdividing pores according their size for research, it found that mainly composed mesopores, laws different types different. porosities total macropores increase, while proportions mesopores micropores decrease. dimensions each group samples all within range 2–3, dimension value increases with increase cycles, showing regular characteristics. Micropores some do not possess basically satisfies rule larger diameter, complex structure. (3) Both type I II toughness decrease most when 100%. 40 decreases reach 23.578% 30.642%, respectively. closely related porosity internal linearly negatively correlated toughness. development macropore key factor affecting performance. (4) continue develop. increases, diameter enlarges, proportion rises, resulting damage When bearing loads, expansion connection cracks intensify, ultimately leading failure can provide important reference stability analysis engineering.
