Abstract:

Rheology is basic mechanical property of rock and soil media. For the slope,rheological property of rock and soil media is one of the important reasons for the large deformation and loss of stability. The time-dependent behavior of rock mass is one of the important factors, that influence the deformation and long-term stability of the slope. Based on coupling of long-term prestress loss of anchor tie and slope creep, a new improved Burgers model is built; and the theoretical function of long-term prestress variation is put forward. By comparison with the experiment result, which gets the viscoelastic rheological parameters of suggested model. The comparison between the rheological model and experimental result shows that the generalized Burgers model is right and reasonable.

Key words: slope, rheological effect, generalized Burgers model, coupling
