A Nonlinear Creep Model of Rock Salt and Its Numerical Implement in FLAC3D

الملخص EN

Creep characteristics are integral mechanical properties of rock salt and are related to both long-term stability and security of rock salt repository.

Rock salt creep properties are studied in this paper through employing combined methods of theoretical analysis and numerical simulation with a nonlinear creep model and the secondary development in FLAC3D software.

A numerical simulation of multistage loading creep was developed with the model and resulting calculations were found consequently to coincide with previously tested data.
