Abstract Because of differing structural planes in the rock masses surrounding tunnels, rock masses often consist of different types of structures, such as massive structures, stratified structures, classic structures, and loose structures. Differences between the structures makes the deformation mechanisms of a rock mass complicated and diverse. Elastic deformation and plastic deformation are the main deformation mechanisms of massive rock masses, flexural deformation is the main deformation mechanism of stratified rock masses, rolling and sliding deformation is the main deformation mechanism of classic rock masses, and squeezing deformation and relaxing deformation are the main deformation mechanisms of loose rock masses.
