In order to study the uniqueness of the displacement back analysis of isotropic viscoelastic rock mass, an analytical solution for the radial displacement of a circular roadway in a transversely isotropic viscoelastic rock mass was derived from the principle of elastic and viscoelastic correspondence principle. The uniqueness of the back analysis of displacement in transverse isotropic rock mass was studied according to the identifiable conditions of parameters. The results show that only knowing the displacement of the measuring point can not uniquely invert all the parameters. It is possible to uniquely invert other rock mass mechanical parameters only when at least 3 parameters are known in advance. The values of the vertical ground stress and the transverse ground stress have a significant influence on the identification of back analysis. The fewer the parameters to be solved, the more recognizable the parameters are. The initial ground stress parameters have the best identifiability, followed by Poisson's ratio, modulus of elasticity and viscosity coefficient on the isotropic surface, and the modulus of elasticity and viscosity coefficient normal to the isotropic surface are the worst. The research results provide a theoretical basis for the back analysis calculation of rock mass parameters.
