Effects of incompatible deformation on failure mode and stress field of surrounding rock mass

The importance of the incompatible deformation of the deep rock masses is discussed. The mathematical and physical meanings of the incompatible deformation of the deep rock masses are proposed. The method to research the incompatible deformation of the deep rock masses is introduced. The difference between the incompatible and compatible deformation of the rock mass is elaborated. The calculation case of a circular tunnel in the rock masses containing microcracks is given based on the non-Euclidean model. The effects of the incompatible deformation on failure mode and the stress field of the surrounding rock mass is analyzed. The self-equilibrated stresses induced by the incompatible deformation are determined. The influences of the density and the length of microcracks on the self-equilibrated stresses and failure mode are investigated.
