An Energy Criterion for Rheological Failure of Rock and Application in Stability Analysis of Natural High Slope

Rock fracture and its failure with time due to external forces other factors such as fluids, temperature have always been a major concern in rock engineering construction. Based on thermodynamics theory of solid physics, authors propose an energy criterion for rheological rock, which considers two effects: (1) dissipation reduces strength rock; (2) confining pressure increases rock. Subsequently, we apply it stability analysis natural high slope, order indicate influence long rheology during geology process material slope. After giving equation upper limit estimate slide surface according viscoelastic solution stress about slope under action gravity, calculate the relation between sliding dip angle (assuming line straight line) corresponding slid radius arc. The minimum is 105 years older. distribution contour lines at each point shows that points near face shorter times. results explain topographic feature mountains some extent also one causes topography forming It indicates provides base relating time.
