Numerical simulations of the creep characteristics of the structural plane of rock mass are very useful.
However, most existing simulation methods are based on continuum mechanics and hence are unsuitable in the case of large displacements and deformations.
The discontinuous deformation analysis method proposed by Genhua is a discrete one and has a significant advantage when simulating the contacting problem of blocks.
In this study, we combined the viscoelastic rheological model of Burgers with the discontinuous deformation analysis (DDA) method.
We also derived the recurrence formula for the creep deformation increment with the time step during numerical simulations.
Based on the minimum potential energy principle, the general equilibrium equation was derived, and the shear creep deformation in the structural plane was considered.
A numerical program was also developed and its effectiveness was confirmed based on the curves obtained by the creep test of the structural plane of a rock mass under different stress levels.
Finally, the program was used to analyze the mechanism responsible for the creep features of the structural plane in the case of the toppling deformation of the rock slope.
The results showed that the extended DDA method is an effective one.
