Identification of Nonlinear Rheological Parameters of Medium-Strength Marble Rock


Article Preview

The rheological behavior of rocks has been more and more important to predict the long-term deformation of rock engineering. We select a typical medium-strength marble rock as a research object to study the long-term stability of large-scale underground caverns. Some dry and water-saturated rock specimens are used to perform the uniaxial compressive test and the uniaxial compressive creep test. Then a non-constant-parameter damage rheological constitutive model for this medium-strength marble rock is put forward based on the in-situ geological data and uniaxial compressive rheological test results. The least square method based on search mode is utilized to perform the identifications of the rheological parameters. According to the test curves, the related rheological parameters are obtained through inversion analysis on a basis of the non-constant-parameter damage rheological constitutive model, which can provide more accurate rheological parameters for long-term stability analysis of actual projects.
