Abstract：In order to understand the deformation characteristics and instability mechanism of tunnels under the action of wind oxidation,this study establishes an evaluation index system for the degree of rock wind oxidation based on engineering measurements and laboratory rock mechanics experiments.Similar simulation experiments are conducted to determine the simulation ratios of tunnel surrounding rocks with different degrees of wind oxidation.A self-developed similar simulation experimental platform is methods such as digital speckle pattern interferometry and acoustic emission testing are employed to analyze the deformation character-istics and macro-and micro-failure conditions of tunnels under different wind oxidation experimental condi-tions.Through experimental simulation analysis,the evolution process of roof deformation and macroscopic fail-ure characteristics under different types of wind oxidation are obtained.The experimental results can provide a theoretical and experimental basis for the study of tunnel stability under complex conditions of wind oxidation.
